Dynamics of Rolling Stock Wheels and Track Interaction in Areas of Welded Rail Joints Crush

Abstract

Finite element models of a rail crushed in a welded joint area and fixed on an elastic damping foundation and a car wheel have been developed. An algorithm has been developed to calculate quasistatic and impact forces during a wheel rolling at different speeds. Experimental studies have been carried out to determine vertical forces in the crushed area of the welded joint at a depth of 1.8 mm using the strain measurement method on the rail web neutral axis.
