粗糙峰接触研究成果及最新进展

Advances in Studies on Asperity Peak Contacts

工程材料的接触过程中,微观上真正的接触并不是在物体表面上,而是存在于一些称为粗糙峰的不连续区域中。粗糙峰的性质决定了工程材料接触性质。传统的粗糙峰的研究由于手段的单一,有着五个基本假设,而近年来随着研究方法的丰富,特别有限元方法的引入使得粗糙峰的研究能够考虑更多的因素,传统的假设也被研究者考虑。文章在回顾了传统粗糙峰模型的同时综述了现在粗糙表面接触中研究中最新的热点:粗糙峰相互影响和圆柱形粗糙峰的研究。

Contact of rough surface in engineering applications occurs in the discontinuous regions called asperity peak.So the contact properties of engineering materials depend on the properties of the asperity peak.There are five basic assumptions in the traditional study of asperity peak,with the developing of research methods recently,especially the use FEM,makes the study of asperity peak be able to consider more factors as well as the traditional assumptions.This paper reviewed the traditional asperity peak model and summarized the advanced hottest theme research on asperity surface contact： research on interaction between asperity peak and cylindrical asperity peak.
