LATERAL DYNAMICS OF RAILWAY WHEELSETS RUNNING ALONG A CONTINUOUS ELASTIC SUPPORT TRACK

Abstract

There is an important role in the lateral dynamical processes of the railway wheelset running along an elastic support track. This investigation shows a method for examining the wheel/track lateral dynamical model when the track is described as a homogeneous discrete elastic support beam, and the lateral creep force as a function of the lateral velocity of the wheelset and the track, exciting the wheelset, and the track, too. So the wheelset and the track form a lateral dynamical system. It can be described by a second-order general differential equation, and two fourth-order partial differential equations for the wheelset and the tracks, and those can be solved by using a linear creep force excitation as the connection conditions between the joint differential equations.
