| Abstract: | A kind of dynamic wheel-track contact element is designed by the technology of ANSYS User Program Features. A 3D vehicle-bridge-pier coupling dynamic model is built by the element with combination of the vehicle and the substructure. Simulation analysis on the Dashihe Bridge is carried out. Its transversal vibration characteristic reappears well when the freight train passes through it. |
