摘要
工程表面在微观尺度上是粗糙的,粗糙表面之间的接触状态对于多种物理现象都有重要影响,因此,粗糙表面间的接触建模方法一直是摩擦学领域研究的热点.由Greenwood和Williamson提出的GW统计接触模型是最受认可的粗糙面接触模型,回顾了基于统计分析的粗糙面接触模型的发展,根据对GW模型主要缺点的改进,介绍了统计接触模型的研究现状,总结了统计接触模型未来可能的研究热点.
The engineering surface is rough on microscopic scale.The contact behaviour between rough surfaces has a significant influence on various physical phenomena.Therefore,the method of contact modeling between rough surfaces has been a hot topic in the field of tribology for a long time.The GW statistical contact model proposed by Greenwood and Williamson is the most recognized rough surface contact model.The developments of rough surface contact model based on statistical analysis were reviewed in the present work.According to the improvements of the main defects of GW model,the research status of the statistical contact model was introduced.Some possible research hotspots of the statistical contact model in the future were summarized.
