The fretting wear characteristics of spherical/spherical lateral contacts under different load conditions, contact angles, and the number of fretting cycles are studied. A spherical/spherical lateral fretting wear model is established in ABAQUS software. A UMESHMOTION subroutine for spherical/spherical contact models is written to simulate the fretting wear based on the energy model and the Fortran language. The results show that as the load increases, the contact width increases significantly and the wear depth decreases. It is also found that the rate of change of the wear depth gradually increases in the central portion of the contact area, and is relatively smooth in the contact edge portion. An increase in the magnitude of the moving load causes a small increase in the contact width and a significant increase in the wear depth. The rate of increase of the wear depth at the edge of the contact area gradually increases and the rate of increase of the wear depth at the center of the contact area changes linearly. As the contact angle increases, the contact form gradually changes to a positive contact. Meanwhile, the wear depth variation shifted from a “U” shape to a “W” shape, which caused the wear depth to decrease significantly at the contact center and eventually approach zero as the adhesive area appeared. In addition, with an increase in the number of fretting cycles, the wear depth was almost unchanged at the contact center portion but significantly increased at the edge portion.

研究了不同载荷条件，接触角和微动循环次数下球形/球形横向接触件的微动磨损特性。在ABAQUS软件中建立了球形/球形横向微动磨损模型。编写了用于球形/球形接触模型的UMESHMOTION子例程，以基于能量模型和Fortran语言模拟微动磨损。结果表明，随着载荷的增加，接触宽度显着增加，磨损深度减小。还发现，磨损深度的变化率在接触区域的中心部分逐渐增大，并且在接触边缘部分相对平滑。移动载荷大小的增加导致接触宽度的小幅增加和磨损深度的显着增加。接触区域的边缘处的磨损深度的增加率逐渐增加，并且接触区域的中心处的磨损深度的增加率线性变化。随着接触角的增加，接触形式逐渐变为正接触。同时，磨损深度变化从“ U”形转变为“ W”形，这导致磨损深度在接触中心显着降低，并随着出现粘合面积而最终接近零。另外，随着微动循环次数的增加，磨损深度在接触中心部分几乎不变，而在边缘部分明显增加。随着接触角的增加，接触形式逐渐变为正接触。同时，磨损深度变化从“ U”形转变为“ W”形，这导致磨损深度在接触中心显着降低，并随着出现粘合面积而最终接近零。另外，随着微动循环次数的增加，磨损深度在接触中心部分几乎不变，而在边缘部分明显增加。随着接触角的增加，接触形式逐渐变为正接触。同时，磨损深度变化从“ U”形转变为“ W”形，这导致磨损深度在接触中心显着降低，并随着出现粘合面积而最终接近零。另外，随着微动循环次数的增加，磨损深度在接触中心部分几乎不变，而在边缘部分明显增加。
