【摘要】 采用非线性有限元法进行了凹坑形表面磨损过程的二维有限元模拟．通过对磨损过程的二维模拟分析发现,在材料表面添加人工纹理不一定能减少材料的磨损．在一定尺寸范围内,凹坑在 UHMWPE 表面的等效应力要大干凹坑在不锈钢表面的等效应力．本文利用 ANSYS 有限元软件获得的结果对于研究非光滑表面磨损机理和进行磨损预报有一定的借鉴意义,而且为其他非光滑形态的研究及其对材料表面的耐磨性影响提供了重要的参考价值．更多还原

【Abstract】 The thesis utilized the nonlinear finite element to analyze wear of two dimensional concave surfaces. The results of two dimensional simulation show that establishing the artificial textures on the material surface is not always reducing wear.The results of the stress analysis show that the equivalent stress of the concave on the UHMWPE surface is larger than that of the concave on the stainless steel surface in the certain scope.This paper gets some mechanics characters by using the software ANSYS.It is very usefnl to studying the wear mechanism of non-smooth surface and predicting the material wear.What is more,this research has impor- tant practical value to apply other non-smooth surface and the anti-wear ability of the material.更多还原
