摘 要:在配流副表面加工微织构并研究其减摩特性。采用正交试验方法进行配流副仿真研究,得到各因素对配流副摩擦影响顺序为:转速>油膜厚度>深度>形状>直径>面积率,得出最优参数组合为:直径400μm、深度200μm的圆球形凹坑、凹坑面积率6%、油膜厚度15μm、转速1500 r/min.分析了微织构配流副的速度场、压力场、动压承载力,并对全油膜进行了仿真。搭建了轴向柱塞泵的配流副摩擦试验系统,在不同负载压力4 MPa、8 MPa、12 MPa和工作流量10 L/min、20 L/min、35 L/min下,对最佳参数的微织构配流副进行摩擦特性试验,试验结果表明,微织构配流盘的摩擦扭矩值比光滑配流盘小,与全油膜仿真结果相验证。最大差值为1.53 N·m,最大减摩率为12.47%.The micro-texture was fabricated on the valve plate surface and its antifriction characteristics were studied.The orthogonal test method was used to conduct the simulation study of the valve plate pair,and the order of influence of various factors on the friction of the valve plate pair was as follows:speed>oil film thickness>depth>shape>diameter>area rate.The optimal parameter combination was obtained as follows:spherical pit with diameter of 400μm and depth of 200μm,pit area rate of 6%,oil film thickness of 15μm,and speed of 1500 r/min.The velocity field,pressure field and dynamic pressure bearing capacity of the micro-textured carrier are analyzed.A friction test system was built for the valve plate pair of the axial piston pump.Under different load pressures(4,8,12 MPa)and working flow rates(10,20,35 L/min),the friction characteristics of the micro-texture valve plate with the best parameters were tested.The test results show that the friction torque value of the micro-texture valve plate is smaller than that of the smooth valve plate,the maximum torque difference is 1.53 N·m,and the maximum friction torque reduction rate is 12.47%.
