Abstract

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.
