Abstract

Computer simulation of rail vehicle-turnout dynamic interaction with mechanical imperfections J. Drozdziel & B. Sowinski Faculty of Transport Engineering, Warsaw University of Technology, Poland. Abstract This paper presents some aspects of modelling of dynamic interaction between conventional railway car and track taking into consideration mechanical imperfections. The imperfections may relate to deviations of geometric parameters against their nominal values or shapes. In our approach, the deviations are described for the single standard turnout and for the wheelsets of the railway car. In order to appreciate the imperfections, mathematical model and computer package has been elaborated. The package collaborates with the Matlab-Simulink environment. Several simulation results are presented to recommend the usability of the approach. They imply a conclusion that specific turnout parameters and analysed deviations of some of them create a vital cause of
