The R & D policy of the industry partners taking part in this project is also developed in such a way that they can use virtual testing more effectively in their R & D work.
Innovative ceramic components for fluid power applications.
Ref: 43104
Improved components in fluid power systems which execute sliding or sealing operations in many cases require high wear resistance, good sliding properties, reduction of moved masses, stiffness and high corrosion resistance respectively. A combination of many of these properties can be satisfied in a by far optimised way by ceramic materials which offer a high potential mainly for the following fields of development in fluid power technology: increased tolerance to particle contamination in hydraulic and pneumatic fluids and use of more inexpensive and less environment-polluting pressure media such as high water-based fluids in hydraulics and oil free dry air in pneumatics. The international competition on the fluid power market makes concepts for economic operation with reduced expenditures on servicing and repair and reduced filtration costs, also using cheaper and environmental acceptable pressure fluids more and more desirable. The objective of his project, investigating ceramic materials for fluid power applications, is the acquisition of theoretical and practical basic knowledge concerning tribological (erosion, stress corrosion cracking cavitation etc.) and fluidic (adherence of surface boundary layers, stick-slip etc.) aspects, the conceptual design and the realisation of fluid power components using ceramic materials and coatings and the verification of the working performance of such components in the developmental scale. Only on the basis of the know-how acquired in this project the selected and other components can be led to a commercially viable state exploiting the potentials of ceramic materials and reducing the component costs to an optimum. The volume of the European market for hydraulics and pneumatics, which is for the most part dominated by SME manufacturing companies, amounts to approx. 6.800 MECU. Thus, Europe is the world's leader in the fluid power industry with a market share of 52,3% of the world market. By the means of product innovation and improvement of the products' performance this strong market position shall be maintained and strengthened.
Modelling Sound Generation and Propagation in Fluid Machinery Systems
Ref: 36425
Fluid machines are a familiar part of everyday life in the home, the workplace and in transportation systems. Virtually all fluid machinery generates sound, and some examples such as motor cycle and aircraft jet engines are notorious for their noise output. It is hard to identify any day to day human activity in which individuals are not exposed to fluid machinery noise. For instance in the BRITE EURAM project no. 5983 (EQUIP), fans, where flow is the main cause of noise generation, have been identified as one of the most important noise sources in machines. Another important aerodynamic source process is regenerated noise in flow ducts, which imposes a major limitation for the performance of compact flow systems. In improving the performance there is also a tendency to increase flow velocities in fluid machines, which increases the importance of flow generated noise. Increased flow velocities also change the sound transmission properties of flow ducts in machines. Overall, the physics of sound generation and transmission in fluid machinery systems is not well understood. The state of the art in the acoustics of fluid machinery falls far short of the requirement for well-developed and comprehensive predictive methods, that can be used for a better acoustical design of these devices. Even physical modeling of the passive components in the ductwork of fluid machines is limited mainly to relatively simple systems, and the understanding of source mechanisms and complex flow/acoustic interaction phenomena is only barely adequate in a limited number of cases.
Low cost power and flow control system for remote subset fields
Ref: 37212
This project demonstrates all the subsystems required to generate and control electrical and seawater hydraulic power. The major subsystems include control, power supply and hydraulically actuated components. Interface engineering, of the concepts, which have been previously developed or tested as discrete components, is included to ensure the assembled system is coherent and complete. Representative components will be fabricated and assembled into a working remote control system.
Enhanced Design of High Pressure Gear Pumps Using Environmentaly Acceptable Hydraulic Fluids
Ref: 31005 or 95-1046
The main objective of this project is to improve the design and manufacturing process of high pressure external gear pumps in order to make the pump compatible with environmentally acceptable hydraulic fluids (ecological oils), extend the service life of the pump for different operational levels, reduce noise effects. These objectives will be achieved by developing and validating new experimental procedures and computational models to assess the performance of gear pumps
Subsea powered autonomous remote control system
Ref: 20238
The current control technique for hydrocarbon production utilises a multiplexed electro-hydraulic control system, to permit a fast response for subsea hydraulic valve operation and allow detailed monitoring information to be collected to maximise recovery. A control umbilical, between the platform and subsea well contains a combination of hydraulic control lines, and electrical lines to communicate and power the subsea control module. The SPARCS system will control a remote subsea well without the use of control umbilicals. The system will comprise of two groups of equipment, a surface controller and subsea control module. The surface controller allows the operator to interrogate and control the subsea system via an acoustic transponder, using seawater as the communication medium. The subsea equipment will consist of Subsea Hydraulic Power Unit with associated motors, pumps, closed loop fluid reservoirs and accumulation, electrical subsea power generation unit operating from a water injection flowline, power generation from sea-water electrolyte batteries is also being evaluated, acoustic transponders for communications, electronics for system control and sensor monitoring, hydraulic valves for tree actuator control, battery system for storage of generated power. SPARCS is highly innovative in that it controls hydrocarbon wellheads without the use of control umbilicals. The subsea systems electrical power is produced by a turbine Generator fitted to a water injection flowline, or alternatively seawater electrolyte batteries. Hydraulic power for operating wellhead and downhole safety valves is produced from a subsea unit, with communication signals for valve control and sensor monitoring using acoustic telemetry. The SPARCS system will be the first integrated autonomous control system used for subsea hydrocarbon production, allowing continual operation without surface intervention for periods up to 2 years.
Development of a processing technology producing new pistons to reduce hydraulic motors prices
Ref: 43205
The development project concerns the application of new techniques in processing Pistons for Hydraulic motors on automated or semi-automated production lines. This new technology aims to reduce the cost production of Pistons to give more competitivity and more power to this kind of motor comparing to traditional thermic motors. Hydraulic motors now cost more than traditional thermal engines, but they present some technical advantages as concerning their fluidity due to the possible controls on each transmission wheel and are very useful for agricultural sector for the tractors vehicles, for fishing sector with the fishing winches and for elevators vehicles. The industrial objectives are clear in terms of reduction of costs (a piston is 15% of the engine price) of time processing, introduction of flexibility in the process, and the new development will also include an automatic capture of pieces by the mean of articulated captors as well as new experiments in deburring system using electrodes and suppressing dangerous tasks such as grinding with emery. The new type of Pistons to produce is not actually being developed in EC, but in Japan (TMK), but at our knowledge the resulting prices have not been cut down enough. All of these industrial objectives must converge towards minimizing the prices of Hydraulic Motors to compete with thermal motor products. This development will ensure more competitivity and more flexibility to adapt more easily the typology of Pistons depending of the market demand.
Hydraulic pressure and flow control valves with enhanced fluid dynamic and wear performance
Ref: 42820
With pressure and flow control valves the energy of the hydraulic fluid is dissipated in a very inefficient manner. Sharp bends and non-ideal flow paths typically cause: considerable vortexing and turbulence, very low discharge coefficients (through orifices), low accuracy of flow control, extraneous heating of the working fluid (which sometimes requires compensation down-stream), excessive pressure losses and power wastage, increased wear of the component and objectionable noise. These leads to reduced component lifetime, increased failure potential, reduced overall efficiency and higher power input. By definition, hydraulic systems will operate at high pressure and in some instances these will be at high temperatures too. Many hydraulic fluids are also flammable. In this respect, failure of a hydraulic valve is very undesirable. It is the proposal of this project that it will be possible to significantly improve the flow dynamics and wear resistance of existing hydraulic pressure and flow control valves by performing an in-depth computational fluid dynamics (CFD) and materials analysis. The main RTD goals and intentions are summarised below: Design, configuration and CFD analysis of a range of alternative flow and pressure control valve systems to minimise vortexing and turbulence by improving fluid flow paths. Identification and evaluation of alternative valve materials (such as ceramics) in order to decrease erosive wear processes and hence increase operational lifetime. To undertake a detailed experimental and industrial testing programme to fully evaluate and optimise the performance of the configured designs. The successful completion of the above will significantly increase the overall efficiency of hydraulic systems as well as reducing power wastage and failure risk.
Development of
switching valves with high operating frequencies for oil-hydraulics
Ref: 16-3300-02-03 or 454
Fast switching valves for high flow valves are a prerequisite to realize efficient switching techniques for hydraulic drives. Switching frequencies of 1 kHz and flow rates of up to 250 liters/minute are intended. As a first stage fluid flow in valves during rapid changes of valve opening is simulated by analytical, experimental, and numerical methods. Results of this should provide the basis for a systematic design of switching principles appropriate for high frequencies and low oil cleanliness.
Flexible Simulation Software for Hydraulic Drive Systems based on the Finite Element Method (FEM)
Ref: 16-3300-02-04 or 462
Modern hydrostatic drives are mechatronic systems where mechanical fluid flow, electronic, electrical, and control processes are interacting in a dynamical way Among these, fluid flow is the most complicated process unless wave propagation or dominated effects are negligible. Using commercial software for computational fluid dynamics hardly permits to include the other processes and suffers from extreme computational effort. The computer code under work should be designed for easy incorporation of the diverse mechatronic components and for time efficient simulation of flow processes in hydraulic components by problem- and component specific Ritz ansatz-functions.
Switching techniques for hydraulic drives
Ref: 16-3300-02-02
Today switching techniques are a standard mean to achieve high efficiency in electric drives but are unknown under this energy saving aspect in case of hydraulic drives. This project aims at finding the basics for realizing this technique and providing thus a feasibility information. It is based on mathematical modelling and experimental verification leading finally to a pilot experiment to make feasibility obvious. Theoretical and experimental work done so far show that this technique can be realized. Further work in the field of laminar- turbulent transition of pulsating fluid flow has to be done to get better mathematical models as a basis for a finer tuning of some design parameters.
Development of sensitive pneumatic switching controls for industrial plant
Ref: 43163
To design and develop a prototype pneumatic switching system for industrial plant and machinery. The system will be touch sensitive to improve operator control, incorporate improved response times down to15 ms, be capable of being installed as an upgrade to existing systems, be cheaper to install and maintain than electrical systems, be devoid of any electrical components and so be suitable for use in installations where there is a fire hazard.
Pneumatic manipulator of stocking for plastic boots controllers by fuzzy logic for injection footwear industry
Ref: 43111
The footwear technology of plastic boot consists of the injection of the upper over a sock lining and than the moulding of the sole onto the upper by an injection machine. A common problem of the bootmakers is the continuous potential danger of serious accidents that can occur to the workman that operates near the injection machine for lasting the sock lining on the aluminium last. This project is aimed to develop a pneumatic manipulator to be enslaved to the rotary machine which is able to last, stitch and cut a sock lining on the last simulating the movements of the hands. To obtain a smooth and adaptive adjusting of the sock lining on the last, the actuators of the manipulator will be driven by fuzzy logic control system.
Investigation of nonlinear control concepts for high performance pneumatic positioning devices
Ref: 14-3280-01-02 or 328-01-01
Nonlinear controller structures for highly nonlinear pneumatically actuated positioning systems are developed in order to improve the system performance. Design techniques of nonlinear controllers are based on nonlinear system theory. By means of exact linearization and diffeomorphic mapping, linear control theory can be utilized. Variable structure control, especially Sliding Mode Control (SMC) and Bang-Bang-Control lead to nonlinear controller structures, which show robust, closed loop system behaviour, whereby desired system dynamics can be influenced in a nonlinear sense. Simulation results show that nonlinear controller structures can be successfully applied for pneumatically actuated positioning systems.
Dynamic operating limit of a hydraulic directional valve
Ref: 2-0939
Dynamic operating limit of a directional valve is determined with the maximum pressure and maximum through-flow, which is still allowed not to interfere a reliable operation. When a directional valve is operated at limit values (i. e. maximum pressure and through-flow) different interfering forces are effective on the valve spool. These can exceed the actuating forces, which are available from the control solenoid and return springs. By means of mathematical modeling and comparison analyses there is necessary to find optimal shape of direction valve which allows a reliable operation at limit pressure and through-flow values.
Modeling, Simulation, and Control Concepts for a Hydraulic Supply Unit to Control Pressure or Flow Rates
Ref: 4945
This summary discusses the development, implementation and investigation of a signal-processor based digital controller, which interfaces with an existing hydraulic supply unit thus increasing its overall system performance. The major objective is to control pressure-level or flow-rate at a point of interest within a hydraulic system (normally outside of the supply unit). Conventional hydro-mechanical components, such as pressure limiting valves or proportional valves, do not achieve satisfactory results. Consequently, a mechatronic approach suggests the use of a digital controller to adjust the supply unit's state so that the desired pressure or flow-rate at this point of interest can be kept within reasonable limits. Investigations based onto the laboratory system have shown that pressure deviations were well within +/- 0.45 bar and flow-rate errors within +/- 0.45 l/min for given disturbances resulting in an significant increase of the overall system performance up to a factor of ten.

Non-linear electromechanical systems with learning
Ref: 3/3.1/CEG/2550/ 95
The theoretical understanding that, in the last two decades, has been achieved concerning the dynamics of non-integrable systems is now ripe to be used in many diverse situations. This is particularly true for the results that now exist on the ergodic theory of chaotic dynamical systems. For example, the fact that a small perturbation grows exponentially in time led to the widespread belief that chaotic systems were uncontrollable and therefore to be avoided in technological applications. Actually these systems are now known to be controllable and appropriate for very fast and robust control systems. Another field where reasonable progress may be achieved is the simulation and modelling of complex non-linear systems. To have an accurate model of the system is an essential requirement in all control and prediction problems. When dealing with non-linear complex systems it is not usual to have an accurate analytical model. Therefore control and prediction becomes inaccurate and prone to large fluctuations. Hence it would be convenient to design systems where the model improves itself in real time. This implies that the dynamical laws to be built in the system must have learning capabilities. In this proposal several projects will be developed which make use of the modem techniques of non-linear dynamics and connectionist systems. The general aim is to develop systems with dynamical learning capabilities. As the main technological motivations for project we mention the control of electro-dynamic and electro-hydraulic drives, the modelling of complex systems and fast control using unstable trajectories. For clarity the proposal is divided into subprojects. The aims, an overview of the state of the art and technical details will be specified for each one of the sub-projects.
Concept of fully hydraulic-mechanical shock absorber system sensitive to load, dedicated to motorcycle and of general applicability to road transport means
Ref: 42131
The objective of the project is the obtainment of Rear shock-absorber for road vehicles, and motorcycles in particular, featured by variable hydraulic and automatic self-adjusting calibration related to the transported load and, whenever possible, sensitive to acceleration. The aim of the research consists in the development of a technology able to supply a self-powered trim control and an advanced shock absorption law that does not need any computer-aided device or a hydraulic power supply external to the shock absorber. Obtainment of Rear shock-absorber for road vehicles, and motor-cycles in particular, featured by variable hydraulic and automatic self-adjusting calibration related to the transported load and sensitive to acceleration. In particular future Brite - Euram collaborative research project intends to develop a technology based on the: - automation of load variation on the suspension by pneumatic set of pre-load (in motor-cycles the purpose is to optimise the front - back trim); - automatic hardening of the suspension according to the weight; - whenever possible, development, and coupling to the above principles, of a suspension sensitive to the vehicle acceleration.
Novel Epitrochoidal Rotary Pump
Ref: 41919
Although the conventional hydraulic pump design has changed little over the last 50 years, hydraulic systems have to cope with higher performance and duty cycle specification requirements. This is as a result of increasing demands being placed on the design and performance of equipment utilising hydraulic power and control e.g. construction plant equipment. In an effort to improve the performance of existing hydraulic pumps they have identified a new concept in pump technology which they wish to develop further. The project relates to a number of uses for a trochoidal rotary engine design, which has been developed by AC Systems. Primary emphasis within the project will be on the development of a novel and patentable hydraulic pump design. The main RTD goals can therefore be summarised as follows; to prove and develop the epitrochoidal pump design in relation to achieving a pump with at least an equivalent cost and performance to existing pump systems and to demonstrate the extent of the pumps performance through its widespread application and exploitation in industrial hydraulic systems. It has been shown that the concept behind the pump is patentable and the use of trochoidal rotary engine design for hydraulic pumping purposes represents an entirely innovative approach.
Reducing the energy consumption of industrial hydraulic equipment by development of a pressure reducer
Ref: 9400090
The aim of this project is to develop a component for hydraulic systems, which can transform a small flow at a high pressure into a larger flow at a lower pressure (a pressure reducer). It shall substitute the energy demanding throttling used for regulating hydraulic systems today, reduce the flow in the piping of the system which will cut down friction losses in the system, make building of systems with several end user components with fluctuating flow and pressure possible without great energy losses. The project will consist of three parts:
-
The performance of the pressure reducer - theoretical part. Functional analysis of the pressure reducer for typical end users and types of systems. Analysis of the potential for energy savings.
-
Prototype. Design and construction of a prototype in co-operation with Hans Iversen Hydraulik.
-
Implementation. The prototype will be implemented on existing systems for control of function and energy measuring in co-operation with Søndergaard A/S. Finally the result will be put into a report. The pressure reducer should be put into series production. It is expected to be used in both industrial and mobile applications. A preliminary study indicated a potential for energy saving of around 20% of the total electricity spent on hydraulics of totally implemented. In some applications the potential will be much higher (50-70% of the electricity consumption -estimated).

Investigation of the Dynamic Behavior of Servo Hydraulic Drives
Ref: 461
The behaviour of servohydraulic drives is governed by a set of nonlinear, singularly perturbed differential equations with non-differentiable right hand sides. Modern dynamic systems theory is applied to deepen qualitative insight and to derive compact quantitative information. System behavior is described sufficiently by a reduced set of equations, which is obtained if oil compressibility is neglected. Solutions for this set of equations are given by explicit formulae. In this reduced case discontinuities for the pressures can occur which become transition layers for the full equation set. Stability properties too are strongly related to oil compressibility.

Development of Combined Electric/Hydraulic Control and Transport Umbilicals in Long Length Employing a Stranding Method
Ref: 16091
In this project, a version of a stranding method with alternating stranding direction (also known as SZ-stranding) which has been known for some considerable time is to be developed further. To date, this method has been used primarily only for stranding of smaller gauge telecommunications cables, switch board cables and control cables. More recently, this method has also been used in the production of optical fibresteel communications cables. For the production of large-volume combined umbilicals, the method using the tubular stranding process would appear to be the most promising under the technical and economic aspects. The
objectives of this project will be to further develop this stranding method and to employ the method for the production of combined electric/hydraulic umbilicals. It is important to obtain further information on the mechanical behaviour of the stranding elements at the points at which the stranding changes direction.

Autonomous Operation Of A 300 kW Wind Turbine with Hydraulic Transmission Together With a 240 kW Diesel Plant
Ref: 15386
A BOHES 300 kW, 26.5 m diameter wind turbine with hydraulic transmission will be installed at the industrial zone in the city of Waddinxveen. The wind turbine will be electrically coupled to a 240 kW standard diesel engine in order to operate as an autonomous power unit. An advanced control system will keep the electrical parameters (frequency etc) within the acceptable values. The 2-bladed turbine is operational at wind speeds between 5 and 25 m/s, reaching its nominal power at 13 m/s. The 300 kW hydraulically driven synchronous generator is expected to generate about 310 MWh, while the diesel engine will generate about 150 MWh/yr. The estimated payback time is still high due to the nature of the project and the innovation incorporated (hydraulic transmission, etc).

160 kW Windturbine with Hydraulic Transmission at Schiedam
Ref: 16013 or
34127
A BOHEMEN 160 kW wind turbine with hydraulic transmission will be constructed and installed at Schiedam in order to cover the electricity needs of an exhibition center. The design is based on the successful one of the 80 kW wind turbine installed at Winsum. The 3-bladed wind rotor directly drives a high torque hydraulic pump with which the wind power is converted to hydraulic power, which is transferred, to the hydraulic motors on the ground. The latter ones drive a synchronous generator. As soon as maximum power is reached, the hydraulic pitch control
keeps the generator power constant.
On-Chip System for A Servo-Valve
Ref: 31417
Until now, a lot of work has been done on microprocessors and their associated macrocells. But only few of them were done for the systems, which include all the analog, digital and power cells on a single chip. Thanks to the new BCD technology from SGS-THOMSON, which integrates microcontroller and power, it is possible to study a component applicable to the large market of mechatronic systems. Based on Thomson-CSF patent and with the co-operation of Citroën for its low cost hydraulic technology, a new type of proportional servo-valve has been developed. It contains a hydraulic spool, a housing, a torque motor and its electronic control. To decrease the price of electronic part for large quantities, the partners of the project intend to develop an on-chip microcontroller based system. This one runs the inner command/control loop of the servo-valve.

Multiphase Pumping System with Piston Pump for Crude Oil Production
Ref: 16373
Due to the vertical position of the cylinders and especially the recess in the piston head accommodating, the cylinder head shape, the liquids are collected in the piston head and are lastly evacuated at increasing rates, which helps the solid particles being contained in the fluid to get back in suspension and be evacuated. Then, when the piston is getting close to top end, the residual dead space is filled with liquids and a small amount of stroke will only be needed to decompress the liquids and cause them to entirely fill the cylinders in the suction phase. As a result of the adjustable pumping rate and the adjustable hydraulic power fluid pressure only the amount of energy required for pumping will be absorbed. It must be noted that the pumping cycle will not change whenever a gas pocket or liquid plug occurs at suction end, which is a very frequent condition in diphasic production. Since none of its moving parts is external this pump will be quite suitable for subsea application. Its remotely controlled operation is extremely simple: after pumping pressure is set to maximum, the number of strokes (flow) is adjusted as a function of the pressure desired in the separator located at the end of the discharge line. The whole pumping system operates fully safety, the pump can generate no pressure likely to endanger the discharge line: direct proportionality between hydraulic pressure and discharge pressure in the line. Safety is also provided when the pump is not operating: suction and discharge valves provide a double barrier to prevent fluids in the discharge line from returning to the wells while they allow fluids to flow freely from the well(s) to the discharge line as long as the discharge line pressure is lower than that in the well(s).
Water hydraulic arc motor/pump
Ref: 42863
Hydraulic power transmission with oil media is widely applied in the industrial applications such as plastic injection moulding, mining, offshore applications and food processing. The inevitable trends in the industry and legislation show very clearly that the oil in the hydraulics should be replaced with less pollutive media such as the most optimal alternative, pure water. The need of oil replacement in the industrial hydraulic systems can be derived from the fact that the industry and the society want to minimize the pollution, improve the overall productivity and minimize the safety risks on different levels of their activation. Technically simple water hydraulic components as valves, and cylinders are commercially available. More developed but still conservative items such as pumps and motors with limited performance are also available. However, the inferior output/weight ratio and performance specification compared to those of oil motors/pumps limits the utilization of the water hydraulics in the industrial applications. To promote the developing of environmentally friendly water hydraulic motors/pumps that meet the industrial needs a completely new design approach should be adopted. The traditional design principles bring along to the water applications severe technical limitations such as sealing and other material problems that are critical for the operation. The core group of companies will adopt a completely new innovative motor concept to become the basis of the new generation
of water hydraulic motors/pumps. The innovative motor concept design principles minimize the number of moving parts and the undesirable forces in the systems thus making it the optimum starting point for the RTD -project. The optimal developing process of such a new concept requires scientific research capability of different but well integrated disciplines as well as financial resources that the individual SME-companies of this proposal do not possess. The research is primarily focused on the integration of water as a media into the new motor concept along with the research and evaluation of new material alternatives. The project is pre-competitive in nature and it will generate research data to facilitate the core group companies to start the planning of a completely new product range. The suggested RTD project aims at the designing and constructing an operating prototype scale motor / pump for the preliminary test phase carried out by the core group companies. The core consists of a group of companies prominent in European SME -companies that are specialized in the hydraulics and water hydraulics design, manufacturing and marketing in the global market. The starting point of the project from the participants point of view is that the exploitation of the results will be immediate and well organised from the very beginning of its activation. The research resources needed will be provided by the world leading water hydraulic research organisation of Tampere University of Technology (TUT), The Institute of Hydraulics and Automation (IHA) with the university technology transfer company Tamlink Ltd.
