SUMMARYA 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 experimented 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.
