Prediction of the rail-wheel contact wear of an innovative bogie by simulation analysis

Abstract

Rail-wheel contact wear is an actual technical problem, which requires special attention especially on vehicles operated on track with curves. An innovative bogie for tram cars with system for setting radial wheelset positon when running along curves was proposed. This paper deals with the prediction of wheel wear by simulation analysis in Simpack software. Obtained results are subsequently processed in a special, by authors created program in order to predict the worn tread geometry. Two cases are compared – wheel wear in case of bogie with working and with blocked mechanism for wheelset position setting.
