| 摘 要： | 应用复合直接迭代法求得了弹流润滑问题的数值解。算例表明，所得的油膜形状和压力曲线具有弹流润滑问题的全部特征，最小油膜厚度与Ｄｏｗｓｏｎ公式的计算值十分接近。同时，求解方法简单，求解范围大，最大赫兹压力可达１．２ＧＰａ，适用于各种载荷、各种速度状况。

| Abstract: | The numerical solution for the elastohydrodynamic problems is obtained with a forword iterative numerical method. Examples show that film shapes and pressure profiles have all the characteristics of the elastohydrodynamics.The minimum of film thickness is almost close to the calculation value of Dowsons formule.The method is simple and fit for calculating different load and velocity. |
