摘要： 采用了推广的平均流动模型及Greenwood和Tripp的粗糙面接触模型，分析了表面波度的幅值和波长对平行滑块气穴润滑的影响。指出表面波度是决定平行滑块油膜形成能力的最主要因素。对于给定的润滑系统，表面存在最佳波度使得油膜形成能力最强。

Abstract: The generalized average flow model and Greenwood and Tripp’s contact model for rough surfaces are used to analyze the effect of surface waviness amplitude and wavelength on the eavitation lubrication of parallel sliders. It is found that surface waviness I the most important factor determining the oil film formation ability of parallel sliders. For a given lubricated system, there is an optimum waviness which makes a best oil film formation ability.

Key words: 表面波度, 滑块, 气穴, 润滑
