A Numerical Method for Counterformal Rolling Contact Problems using Special Boundary Element Method

Abstract

A numerical method is given for the solution of counterformal rolling contact problems. The theoretical basis of rolling contact problems is described in a manner where the physical meanings of the problems can be directly understood. The difference in rolling velocities and the gap in the leading edges of two contacting wheels are calculated as functions of driving forces. Only the contact area is divided into triangular elements. Linear contact pressures are applied on a triangular element. The contribution from a triangular element is calculated analytically.
