THE INFLUENCE OF PERIODIC LOADS ON NON-NEWTONIAN THERMAL ELASTOHYDRODYNAMIC LUBRICATION

The influence of periodic loads on the thermal elastohydrodynamic lubrication (TEHL) in line contacts was investigated numerically in this paper. The Ree-Eyring's theological model was employed to describe the non-Newtonian behavior of the lubricant. The results show that the periodic loads can dampen the changes of TEHL films and increase to some extent the film thicknesses. The dynamic loads with very high frequency can alter significantly the rules of pressure and temperature distributions, the non-Newto...
