Model and Algorithm for Track Element and Vehicle Element,e track-subgrade system once. And in the following computation of each time step, it only needs to assemble the stiffness matrix, mass matrix and damp matrix of the vehicle element into the global stiffness, mass and damping matrices of the track-subgrade system. Therefore, computational efficiency

Analysis of Medium and High-Frequency Vibration for Track Structure,ibration responses of the vehicle and the track structure in the frequency domain are obtained. The advantages of the spectral element method focus on the flexibility of modeling, the generality of the algorithm and the simplicity of programming, and the achievement of high computational accuracy an
