摘要：

To improve the operation efficiency and reliability of axial piston pump, a reliability design method for mechanical efficiency of axial piston pump was presented. Based on the analysis of the instantaneous theoretical torque and instantaneous friction torque loss of a single piston pair, the instantaneous mechanical efficiency model of the whole axial piston pump was established. A reliability analysis method for mechanical efficiency of piston pump was proposed by using the fourth order moment technique, and Monte Carlo method was used to verify the accuracy and timeliness of the proposed method. The influence of the design variables on the reliability of axial piston pump was analyzed by using the reliability sensitivity analysis method. The results showed that the cylinder rotation angle was varied periodically with the reliability of mechanical efficiency of axial piston pump. When the number of pistons was 9, the lowest reliability appears at 20° of cylinder rotation angle. When the number of pistons was 8, the lowest reliability of mechanical efficiency appears at 0°and 45° of cylinder rotation angle. The influence trend of each random variable on reliability was different at any instant. The mechanical efficiency reliability of the piston pump could be improved by properly controlling the sensitive parameters. © 2023 CIMS. All rights reserved.
