Abstract

To obtain stable solutions of asymptotic equations in the inlet and exit zones of a heavily loaded isothermal EHL contact we will employ a regularisation technique which follows from the asymptotic analysis conducted in Parts 1 and 2 of this paper. This regularisation provides stable numerical solutions in a very wide range of parameters which covers the whole practical range of EHL parameters. The success in regularisation of asymptotic equations is extended on the original equations of the isothermal EHL problem. The numerical scheme for regularised original equations of the isothermal EHL problem is developed. Some numerical examples of regularised solutions are presented. It is shown that the regularisation approach works well and produces stable numerical solutions for very large pressure viscosity coefficients. Copyright © 2010 John Wiley & Sons, Ltd.

## Abstract An analytical analysis of a line thermal EHL contact under heavily loaded conditions is proposed. The analysis is based on regular matched asymptotic expansions. In particular, a case of relatively small ratio of rolling and sliding frictional stresses is considered. The problem is redu
