Abstract In elastohydrodynamic lubrication (EHL) contact, the film thickness strongly depends on boundary slips, including velocity slip and thermal slip at the solid–lubricant interface. In the EHL studies published thus far, velocity slip at the solid–lubricant interface has been investigated individually without considering thermal slip. In this study, the effects of both types of boundary slip on film thickness were investigated simultaneously in rolling/sliding contact. Numerical simulations were conducted based on the modified Reynolds equation and energy equation by considering boundary slips on the sliding surface. The results indicate that the velocity slip causes a reduction in film thickness under pure rolling contact, while a shifted surface dimple is formed along the sliding direction due to both velocity slip and thermal slip under zero entrainment velocity (ZEV) contact.

纯滚动和反向滑动接触下边界滑移对热弹流润滑的影响

摘要 在弹性流体动力润滑 (EHL) 接触中，油膜厚度很大程度上取决于边界滑移，包括固体-润滑剂界面处的速度滑移和热滑移。在迄今为止发表的 EHL 研究中，在不考虑热滑移的情况下单独研究了固体润滑剂界面处的速度滑移。在这项研究中，在滚动/滑动接触中同时研究了两种类型的边界滑移对薄膜厚度的影响。基于修正的雷诺方程和能量方程，考虑滑动面上的边界滑移，进行了数值模拟。结果表明，在纯滚动接触下，速度滑移导致油膜厚度减小，
