Calculation of the Dynamic Responses of Rails Subjected to Moving Loads on Ballasted Railway Track

The dynamical responses of railway track has been carried out by different ways. In this work, developing an analytical model for the ballasted which includes two rails connected to sleeper, a fast method calculated dynamic is presented. rail modelled as infinite beams posed on periodically supports are rested viscoelastic foundation. We consider equation in steady-state subjected moving loads. By using Fourier transform together conditions, relation between reaction force and beam displacement frequency domain demonstrated. Then, performing into sleeper laying foundation, can be obtained with help Green’s function. numerical example demonstrates effect support responses.
