中文摘要：

在线接触摩擦副中，非光滑结构单元的凹坑、凸包、波纹、鳞片形态等表面凹坑形貌对其耐磨性有一定的影响，其中凹坑的直径、深度对耐磨性的影响十分显著。以圆形凹坑非光滑形貌为例，采用有限元仿真分析的方法，对非光滑表面凹坑不同直径和深度的磨损过程进行了分析，研究了仿生非光滑表面对摩擦副耐磨性影响的程度。研究结果表明：线性摩擦副工作过程中，凹坑间距为1000μm的条件下，摩擦副表面的等效应力和摩擦力随着圆形凹坑直径的增大而增大，随其深度的增大而呈抛物线增长；且在凹坑直径为100μm、深度为300μm时，矩形块的耐磨性最优。

英文摘要：

As for line contact friction pairs, the surface morphology of non smooth structure unit has a certain effect on its wear resistance such as concave, convex hull, corrugated, scale morphology etc., and the diameter and depth of the concaves have a significant influence. Taking circular pit non smooth surface for an instance, analyzes the wear process of the different diameter and depth pits of non smooth surface and researches the influence degree of bionic non smooth surface on the wear resistance of friction pairs. The results indicate that in the linear friction pairs working process, the equivalent stress and friction on the friction pair surface increases with the increment of the diameter of circular pit and appears parabolic growth with the depth increasing at the conditions of pit spacing of 1 000 μm, and the wear resistance of rectangular piece is the optimal when the pit diameter is 100 μm and the depth is 300 μm.
