Abstract
In the present paper, a frequency domain model for vertical and lateral dynamics and two time domain models for vertical dynamics of the ballasted track are described. All models take into account the subgrade behaviour using halfspace theory. The frequency domain model is discussed in detail with respect to the algorithm for infinite periodic structures which are used for the derivation of the governing equations. As regards the time domain models, emphasis is placed on the particular capabilities to simulate non-linear behaviour. For each model presented in the paper, the results of numerical analyses dealing with vehicle/track interaction are given.
