| Abstract |
The aim of PROHIPP (IP) is to develop, validate and disseminate new knowledge-based and life cycle design methods and manufacturing processes leading to a new generation of high pressure fluid power components for multidisciplinary applications. The focus is in hydraulic cylinders and accumulators which are the kernel of fluid power systems, and will be requested to accomplish with the European Directives on pressure equipment, safety, environment and quality. An important goal in this project is to increase the knowledge of the technical staff of fluid power industries, machinery manufacturers and end-users, via innovative training activities.
Prime deliverables and breakthroughs of the project to support transformation of industry include:
A)New design by categories (DBC) procedures using advanced computational methods based on DBA (design by analysis), life design (promoted by PED-Pressure Equipment Directive), probability risk assessment and probability design methods.
B)Advanced materials such as ceramics, thermoplastics, and enhanced ductile iron castings. Enhanced seals and surface treatments targeting towards zero leakage, and chrome free coatings. Salt bath nitrocarburizing to improve wear resistance, fatigue strength and corrosion resistance. Environment-friendly oils.
C)Improved manufacturing processes such as a) Ultrasonic Improved honing processes, ensuring the uniform roughness quality of cylinder surface, b) Innovative welding methods such as stud welding and electron-beam welding with zero-leakage and higher life resistance, c) New dry orneardry machining processes for piston-rods with hardened surface leading to a reduction of waste products such as sward, coolants and lubricants and free of oil mist problems.
D)Innovative testing and monitoring methods using IT-based testing equipment. Key impacts of the project are: a)Better and safer cylinders & accumulators with adequate correlation; b)Cylinder and accumulator manufacturing with substantial environmental risk
reduction; c)Fostering the transition of fluid power industry towards a knowledge -based design and manufacturing using R&D and training activities; d)Increased world share market of European products against US and Japanese products in the fluid power sector.
The consortium includes 22 partners from 8 different European countries. |
