ABSTRACT
A mathematical model for the simulation in time domain of the dynamic behaviour of a railway vehicle running in tangent track and curve is presented in the paper.
The main features of the model,with particular emphasys on the subject of wheel-rail contact are described, and some comparisons with experimental data coming from line tests are presented.
The topics of wheel rail contact modelling and of defining a suitable, frequency dependent model for the anti-yaw dampers appear from these comparisons to be critical in order to obtain satisfactory results.
