Multi-objective Optimization of Elliptic Opening Offset Parabola Micro-texture in Port Plate Pair of Axial Piston Pump
摘要
Abstract
In order to improve the bearing pressure,friction-wear resistance and loss-volume efficiency of the port plate pair of an axial piston pump,the port plate of a swash-plate axial piston pump was taken as the prototype to study the influence of shape parameters of elliptic opening offset parabola micro-texture(EOOPT)on the bearing pressure and friction coefficient of the port plate pair with the CFD method based on the orthogonal experimental theory.The shape parameters of EOOPT are optimized with the neural network and the genetic algorithm jointly.Then,the response surface analysis was used to study the influence of EOOPT distribution parameters on the bearing pressure,friction coefficient and leakage amount of the port plate pair,and the shape parameters were optimized.Finally,the relative performance of the port plate pair with the EOOPT texture is compared with that of the port plate pair without EOOPT texture.The results show that the bearing pressure of the former is 11.23%higher than that of the latter and that the friction coefficient and leakage amount are reduced by 16.67%and 2.96%respectively.关键词
