Abstract

In this work, Hertzian and non-Hertzian approaches are studied and compared for the computation of wheel/rail normal contact in terms of global dynamics solutions. Hunt- Crossley force model is used for the Hertzian contact model and Kik-Piotrowski model is used for non-Hertzian contact method. Due to its good balance between accuracy and simplicity, Polach method is used for the calculation of tangential forces. The effect of wheelset yaw motion on the Hertzian and non-Hertzian contact behaviour is the focus in this work.
