Numerical Analysis for the Maximum Rise in Temperature of Point Contact Elastohydrodynamic Lubrication

A simplified solution to the point contact elastohydrody-namiclubrication is presented in this paper. By simultaneously solving the energy equation and the surface temperature equation temperature distributions of three dimensions in contacts are obtained based on pressure and film thickness determined in calculations of isothermal EHL. A group of formulas of the maximum rise in temperature of film and contact surfaces is proposed, which has been verified by experimantal results.
