润滑油膜通常很复杂,无法用理论分析预测其流量和压力分布。但是如果把油膜想象成简单单元组成的网络,则一台计算机可以很便当地预测它们的合成效应。这种方法的理论有许多是从有限元应力分析中借用的。
Lube films are often complex and can not be predicted theoretically to predict their flow and pressure profiles. But if you think of a film as a network of simple cells, a computer can easily predict their combined effects. Many of the theories of this method are borrowed from the finite element stress analysis.
