  • The computational accuracies and efficiencies of different methods for solving dynamic rail model were investigated with vehicle-track nonlinear coupling dynamics model. The methods were modal superposition method based on analytical expression, modal superposition method based on FEM, and direct integration method based on FEM. Rail was modeled by Bernoulli-Euler beam or Rayleigh-Timoshenko beam, and rail model was divided by different types of elements. The response of vehicle-track coupling dynamics was solved with explicit integration method. Calculation result indicates that the computational time of direct integration method based on consistent mass matrix is 28.8 times than that of modal superposition based on analytical expression when rail is modeled by Bernoulli-Euler beam and track excitation frequency is lower, and the computational accuracies of the methods are nearly same. The response influence of rotatory inertia for Rayleigh-Timoshenko beam in vehicle-track coupling dynamics model can be neglected when rail is modeled by Rayleigh-Timoshenko beam and track excitation frequency is lower. The computational time of modal superposition method based on analytical expression is 64.5% slower than that of hybrid element.
