Abstract

Spin in frictional rolling contact can cause large stress which is the key to understand and predict wear and fatigue behavior of wheels and rails. So far the accepted solution is developed in elasticity and statics by Kalker [1] in his computer code CONTACT with a Boundary Element Method (BEM). In this paper, a new approach with the Finite Element Method (FEM) is presented. It is demonstrated with a 3D model of a wheel of coned contact surface rolling over a cylinder. The model is validated with Hertz theory and CONTACT for both the normal and the tangential solutions It has the potential to take into account of plasticity and continuum dynamics.
