Abstract
It is known that geometrical irregularities of the rail head rolling surface produce additional force when the train runs on track. This force can be quite significant and should not be neglected in the analysis, especially when one deals with high speed railways. In this paper, an analytical method of modelling of such irregularities is presented, along with procedure of their stochastic simulation. The detailed description of this approach is associated with its practical application to the analysis of the rail track dynamic response to moving train. The type of imperfections is chosen randomly, leading to stochastic function which describes their distribution along the track. The system response to moving train is described by two layer model which allows to consider all important elements of rail track such as rails, sleepers, rail pads or under sleeper pads. This previously developed model allowed to analyse the dynamic response of rail track in the case of four forces, mainly due to complex computational procedure needed to apply. In this paper, the improved procedure is used, which allows to calculate the track response to the whole passing train.
