求出了高速极重载工况下线接触热弹性流体动力润滑问题的数值解，并对摩擦副进行了应力分析。指出粘度高和粘压系数大的润滑油虽可增加油膜厚度，但亦会加速表面的疲劳磨损。

Analysis of Thermal Elastohydrodynamic Lubrication at High Speed and Extremely Heavy Load

Numerical solutions to the line contact thermoelastohydrodynamic lubrication problem and internal stresses at the subsurface with respect to high viscosity and low viscosity oils, respectively, under high speed and extremely heavy load, have been obtained based on our previous work on the thermoelasto hydrodynamic lubrication of the sliding surfaces with zero entrainment velocity. By analyzing the corresponding results and comparing them with that of the conventional line contact thermoelastohydrodynamic lubrication, it is found that the lubricating oil of high viscosity and large viscosity pressure coefficient accelerates the surface fatigue, though an increased oil film thickness is recorded therewith.
