Long train simulation using a multibody code

ABSTRACT

The work deals with the simulation of long trains in traction condition using a multibody code. The proposed approach consists of the use of mixed models of detailed and simplified vehicle sub-models in order to allow the simulation of the longitudinal dynamic of the entire train, and the analysis of the wheel/rail forces for the detailed sub-models. In this way, it is possible to investigate the effect of the longitudinal efforts on the wheel/rail forces and, more specifically, on the vehicle safety. The vehicle and track configuration is taken from the Benchmark on longitudinal dynamic of trains proposed by the Central Queensland University.
