摘　　要：利用ANSYS模拟了凹坑型微造型表面的磨损过程。模型利用Archard磨损方程动态地调整接触面的几何变形,考虑了接触面几何形状对磨损的影响。对干摩擦条件下光滑型和微造型2种表面的压力分布、最大磨损深度变化、磨损深度分布进行了比较。结果表明,表面微造型有助于减少磨损,利于维持接触面几何形状的一致性,从而延长摩擦副的寿命。The simulation of the wearing process of concave micro-texturing surface was performed with the finite element software package ANSYS.The effect of the changing of contact geometry on wear was considered using Archard wear equation to update the geometry of the contact region.The pressure distribution,the variation of max wear depth and the wear depth distribution of micro-texturing surface under condition of dry sliding were compared with those of smooth surface.The result shows that surface micro texturin...
