Thermal elastohydrodynamic lubrication of infinite line contact rough surfaces considering pressure and shear flow factors

Abstract

A full numerical solution of a thermal elastohydrodynamic lubrication of infinite line contact rough surfaces considering pressure and shear flow factors is obtained. The modified average Reynolds equation, elasticity equation and energy equations are solved simultaneously using a modified Houpert and Hamrock fast approach. The present study demonstrates an efficient computational scheme and the combined effects of the stochastic surface roughness with thermal actions on the bearing characteristic with a wide range of load, rolling speed and roughness parameters.
