| 摘 要： | 提出了等温线接触弹流问题的完全数值解，通过逆解迭代计算方法，获得了不同工况条件下的油膜压力分布、油膜厚度和油膜形状。在计算过程中引入变形矩阵计算弹性变形，利用变形逆阵修正压力分布，都取得了令人满意的效果。提出的计算方法适于求解在工程实践中常遇到的重载线接触问题，所得到的计算结果中最大Ｈｅｒｔｚ接触应力与 润滑油的压粘系数之积为３８．９３。结论与Ｄｏｗｓｏｎ等人的理论是基本—致的。

| Abstract: | A numerical solution for the elastohydrodynamic line contacts problem under heavy loads is presented, and the corresponding method which makes use of the inverse iteration is also described. The method is applicable to heavily loaded line contact problems in engineering practice. The results were obtained at maximum Hertzian pressure of 1.2 GPa. Solutions are presented showing the effect of speed, load and the influence of the pressure coefficient of viscosity of the lubricant on film thickness and pressure distributions. |
