摘要
通过数值解研究了固体表面的横向粗糙峰对钢球与玻璃盘形成的热弹流润滑接触区压力、膜厚以及温度分布的影响。计算中假设钢球是静止的,即滚滑比为2。结果表明在粗糙峰出现的位置上,压力、温度均有急剧的增加,并且固体表面的凹陷现象也变得更加复杂。
The influence of a transversely oriented asperity on the distribution of the pressure, film thickness and temperature in the contact region of thermal EHL was numerically investigated. The steel ball was assumed to be stationary, i.e. the slide/roll ratio was equal to 2. Numerical results revealed that drastic increasing in pressure and temperature occured associating the asperity, and the dimple phenomena on the solid surface became more complicated.
