Elasto-hydrodynamic lubrication of point contact under combined rolling and squeeze film motion

In this paper a numerical solution to the problem of elastohydrodynamic lubrication of point contact under combined rolling and squeeze film action has been obtained. The lubricant is considered as Newtonian and Reynolds' hydrodynamic equation and the elasticity equation are solved simultaneously for semi-infinite solids. The effects of various loads, rolling speeds, squeeze velocities, ellipticity parameters and material parameters on the pressure distribution and lubricant film thickness have been investigated and the results obtained are presented in the paper.
