摘要

摘要: 为了提高轴向柱塞泵配流副承载性能、抗摩擦磨性能及容积效率，以某型斜盘式轴向柱塞泵配流盘为原型开展研究。首先，依据正交实验理论采用CFD方法研究椭圆开口偏置抛物线微织构(Elliptic opening offset parabola micro texture，EOOPT)形状参数对轴向柱塞泵配流副承载压强、摩擦因数的影响规律，并联合运用神经网络和遗传算法对EOOPT的形状参数进行优化设计。其次，运用响应面分析方法研究EOOPT分布参数对配流副承载压强、摩擦因数和泄漏量的影响规律，并对形状参数进行优化设计。最后对最优特征参数EOOPT织构化的柱塞泵配流副和未织构的相关性能进行对比分析，结果表明，前者的承载压强较后者提高11.23%，摩擦因数和泄漏量分别减低16.67%和2.96%。

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.
