Abstract The vertical coupling dynamic model of vehicle-track is established by means of modal analysis and by utilizing Wilson-θ numerical integral method, the random response of rails are achieved. Based on random process over-crossing theory, dynamic response reliability of rail under various over-crossing hypothesis and extremum distribution are obtained, and then it is compared with the result of numerical simulation calculation. The results indicate that for lower over-crossing limit, the calculation result of Gumbel-distribution method is theclosest to the exact value; while for high over-crossing limit, Gauss-distribution has the best effectiveness.
