Abstract
Numerous studies have been conducted on hydraulic systems operating under high pressure. However, such systems are difficult to realize because of mechanical limitations as a result of tribological problems between relative sliding parts. Design techniques, manufacturing techniques, and tribological characteristics must be improved or innovated to operate such systems under increased pressure. The stress distributions and optimum design factors needed to satisfy these requirements under maximum pressure are determined by analyzing the stress on the valve plate of a hydraulic axial piston pump. This pump is among the most important relative sliding parts. As per the result of the analysis conducted using an orthogonal array, the extent of the influence of the design factors on maximum stress value is ordered as follows: [z > M > h > r]. Moreover, the maximum stress value of the optimum model is 13.3% lower than that of the standard model. Results also show that the stress characteristic of the optimum model is more stable than that of the standard model.
