Abstract

A complete numerical solution of thermal compressible elastohydrodynamic lubrication of rolling /sliding contact was achieved to determine the effect of inlet boundary condition on the film shape,film pressure, and film temperature in an elastohydrodynamic line contact problem.The direct iterative technique is used to solve the simultaneous system of Reynolds, ,elasticity , andenergy equations for different locations of inlet oil fed . The effect of various load, speed , and slipconditions have been investigated . the results indicate that the effects of starvation are an increaseof oil film temperature and decrease in oil film thickness so that the temperature effect aresignificant and can not be neglected.
