Surface topography has an important effect on the wear resistance of contact surfaces. Non-smooth surfaces have stronger wear resistance than smooth surfaces. In this paper, the sliding wear characteristics of the surface of a quadrangular pit formed by ball-end milling were studied. Using the Archard wear model and the UMESHMOTION subroutine in ABAQUS software, the finite element simulation analysis of the sliding wear process was performed under dry friction conditions. Combined with finite element simulation data, the contact area, contact pressure, wear zones and the relative wear rate of the quadrangular pit topography with different sizes were analyzed, and the relationship between the quadrangular pit size and wear resistance was obtained. Based on Grey System Theory, the grey incidence between the relative wear rate of the topography surface and the areal surface roughness was obtained. Based on this, a zeroth order four variable grey model, GM(0, 4), for determining the...

球头铣削形貌的表面耐磨性分析与预测

表面形貌对接触表面的耐磨性有重要影响。非光滑表面比光滑表面具有更强的耐磨性。本文研究了球头铣削形成的四角形凹坑表面的滑动磨损特性。使用ABAQUS软件中的Archard磨损模型和UMESHMOTION子例程，在干摩擦条件下对滑动磨损过程进行了有限元模拟分析。结合有限元模拟数据，分析了不同尺寸的四角形凹坑形貌的接触面积，接触压力，磨损区和相对磨损率，得出了四角形凹坑形貌与耐磨性之间的关系。基于灰色系统理论，得到了形貌表面的相对磨损率与表面粗糙度之间的灰色关联。基于此，用于确定...的零阶四变量灰色模型GM（0，4）。
