Abstract

The surface topography has an important influence on the friction and wear characteristics of the contact surface. In this paper, the topography surface after the ball-end milling is taken as the research object, based on the Archard wear model, through the finite element simulation analysis method, the quadrilateral pit topography surface and the ideal smooth surface wear characteristics are compared and analysed, and found that the surface of the quadrangular pit topography has more excellent wear resistance. Then, using the basic principles of the grey system theory, quantitative analysis of the relevance between the real contact area of the topography surface and the surface roughness parameters, it provides a useful idea for the study of friction and wear characteristics of topography surfaces.

摘要

表面形貌对接触面的摩擦磨损特性有重要影响。本文以球头铣削后的形貌面为研究对象，基于 Archard 磨损模型，通过有限元仿真分析方法，对四边形凹坑形貌面与理想光滑面的磨损特性进行比较，得出分析，发现四边形凹坑形貌的表面具有更优异的耐磨性。然后，利用灰色系统理论的基本原理，定量分析地形表面的真实接触面积与表面粗糙度参数之间的相关性，为地形表面摩擦磨损特性的研究提供了有益的思路。
