摘要：A three-dimensional ballastless track model was established using a finite element method to simulate the rail condition before and after rail break. The distribution of the rail longitudinal stress was analyzed under certain thermal stress. In addition, experiments were also conducted in order to validate the simulation results using rail longitudinal stress test equipment. It was found that the simulation results agreed reasonably well with the experimental results. The tests show that the simulation results could correctly predict the longitudinal stress distribution in the rail. Finally, rail longitudinal stress distributions under different thermal stress were calculated using this model; this is helpful for future application to determine when and where there may be a rail break.
