Modelling of railway vehicle movement considering non-ideal geometry of wheels and rails

Abstract

A model of railway vehicle movement is presented. This model takes into account arbitrary shape of wheel and rails. Therefore models of contact of surfaces of arbitrary geometry are built in. The contact forces are found with possibility of choice from methods of rolling contact mechanics. The shape irregularities cause vibrations, therefore a model of track and its rails, sleepers and ballast is incorporated and also the vehicle model includes vibration-damping elements. Overall it makes a complete model of the vehicle movement with focus on the wear prediction and vibrations due to the corrugation.
