Abstract

A numerical model of surface temperature rise in elastohydrodynamic lubrication start up process is presented. The frictional heat flux is modeled as the product of lubricated contact pressure or solid contact pressure with its respective coefficient of friction. The temperature rise is calculated by numerically integrating the solution of point heat source moving over a half space. The constant speed restriction is removed to allow calculation of temperature rise on a surface with a variable speed. The FFT method is incorporated to speed up the temperature rise calculation. Surface temperature rise in elastohydrodynamic lubrication start up condition is calculated, for the case when speed increase from zero to desired speed occurs in one step and the case when speed is linearly increased to desired speed.
