ABSTRACT
This chapter describes a non-linear static model of the railway superstructure. The presence of the track non-linear behaviour under wheel load is very well known. With the quick development of the new types of track elements particularly clips pads and sleepers, came the need for improved methods of analysing track stresses. The mathematic model of the railway track response presented here includes the various types of non-linear behaviour of the elements of fastening system and gravel bed. The software application of the presented model was used for simulation of many practical tasks. The good agreement between simulated and measured results was observed in the case of the laboratory inclined test simulation. The strain gauges measuring in the track is preparing for the model verification for the case of the track response prediction. The chapter describes overall model of the track can be split into two relatively independent submodels: the sleeper model and the fastening system model.
