Thermal elastohydrodynamic lubrication of line contact rough surfaces using flow factor method

摘要

A complete solution of a thermal elastohydrodynamic lubrication (EHL)of rolling/sliding rough surfaces is obtained. The modified average Reynoldsequation, elasticity equation and energy equations are solved simultaneouslyusing a modified Houpert and Hamrock fast approach. The dimensionlesspressure, film thickness, mean film temperature and surface temperature distributionsare obtained for various values of surface roughness parameters.The results are compared with that of isothermal rough EHL and thermalsmooth EHL. The inclusion of thermal effect has significantly influenced thebearing characteristic for rough EHL problem.
