5/26
Prediction of the component/system behaviour for:
• Reduction of the number of prototypes and of experimental tests• Optimization of the performances (increment of the efficiencies)• Finding solutions for possible malfunctions
Type of domain
• Fluid (flow rate, pressure, temperature and so on)• Solid (contact stress, wear and so on)
• Increased rated pressure from 210 to 250 bar• Added new displacements (10 and 180 cc/rev)
24/26
Intensive testing
• 10 test benches for parallel runs• Most powerful 250 kW full qualification test bench• Time for qualification: 2 to 3 months based on official test specification
