摘要

摘要: 以织构化配流副为研究对象，分析了织构化配流副的稳态受力和瞬态受力情况，建立了织构化配流副的数学模型和基于Simulink的仿真模型，并以配流副间油膜厚度为考察对象进行研究。结果表明：相对于普通配流副，压力突变时，织构化配流副的油膜厚度变化更小，油膜厚度的动态性能参数均有一定程度的提高。动态特性与油膜刚度相关，油膜刚度越大越有利于配流副的动态特性的提高。油膜厚度近似为零时，织构化配流副的压缩效应有利于配流副避免固体接触。

Abstract: The textured port pair in axial piston pump is considered as the research object in this paper, its steady force and transient force is analyzed in detail, its mathematical model and simulation model based on the Simulink software are established, and the oil film thickness is taken as the parameter to be examined. The results show that comparing with the ordinary port plate pair, the textured port plate pair has smaller change in the oil film thickness when the pressure is suddenly changed, and the dynamic performance of the oil film thickness has been enhanced to a certain extent. The dynamic characteristic of the oil film thickness is related to its oil film stiffness, the larger the oil film stiffness is, the more benefits is obtained for dynamic characteristics of the port plate pair. The compression effect of the textured port plate pair can avoid its solid contact when the oil film thickness is approximately zero.
