INVESTIGATION INTO THE DYNAMICAL AND WEAR PROCESS OF A RAILWAY WHEELSET, HAVING TWO WHEELS WITH GRAVITY POINT ECCENTRICITIES

Abstract

The goal of the article was to provide a limit allowed to the gravity point eccentricities (GPE) of wheels, which still does not have a major impact on the dynamics and running safety of the railway wheelset. The other goal of this investigation was to examine and to create a model which is capable to tackle the development of circumferential wear process (CWP) as the consequences of GPEs. During the investigation also the dynamical influence of irregularly worn wheels was analyzed. The development of irregular circumferential wear process of wheels is of great importance, because of its great impact on the operation safety of high speed vehicles.
