摘要: 本文采用多重网格法和多重网格积分法得到光滑表面凸轮-滚子推杆线接触时变热弹流问题的数值解。首先，给出了数个凸轮转动角度所对应的压力、膜厚和温度曲线。在纯滚动条件下，接触区中的温升非常小，可以忽略。一个周期内油膜特性曲线的变化揭示出压力和膜厚。最后，研究了较大滚子半径对油膜特性的影响。
Abstract: In this paper, the multigrid method and multilevel multi-integration technique are used to obtain the numerical solution of thermal EHL in smooth line contact for a cam-roller mechanism. The pressure, film thickness and temperature rise profiles at a number of angular positions of cam are presented. The thermal rise is negligibly small in the cam-roller contact. The characteristics of the oil film are given. Then, a roller with larger radius is studied to show the variations of oil charac-teristics.
