Elastohydrodynamic lubrication (EHL) is a type of fluid-film lubrication where hydrodynamic behaviors at contact surfaces are affected by both elastic deformation of surfaces and lubricant viscosity. Modelling of contact interfaces under EHL is challenging due to high nonlinearity, complexity, and the multi-disciplinary nature. This paper aims to understand the state of the art of computational modelling of EHL by (1) examining the literature on modeling of contact surfaces under boundary and mixed lubricated conditions, (2) emphasizing the methods on the friction prediction occurring to contact surfaces, and (3) exploring the feasibility of using commercially available software tools (especially, Simulia/Abaqus) to predict the friction and wear at contact surfaces of objects with relative reciprocating motions.

弹性流体动力润滑（EHL）是一种流体膜润滑，其中接触表面的流体动力行为受表面弹性变形和润滑剂粘度的影响。由于高度的非线性，复杂性和多学科性质，在EHL下对接触界面进行建模具有挑战性。本文旨在通过以下方法来了解EHL的计算建模技术，即：（1）考察边界条件和混合润滑条件下接触面建模的文献；（2）着重介绍接触面发生摩擦的预测方法，以及（3）探索使用市售软件工具（尤其是Simulia / Abaqus）预测相对往复运动的物体接触表面的摩擦和磨损的可行性。
