Building the multi-rigid-body dynamic model was the traditional way to proceed with the riding quality of the vehicle. This method did not consider the natural vibration characteristics of the component, the reliability of the research results was doubtful. In order to achieve more accurate simulation results, the rigid-flexible coupling model was adopted. Based on the ADAMS/Rail module to build the vehicle multi-rigid-body model, it considered that the vehicle was not a complete rigid-body and the vibrations of the body and the bogie of the vehicle in the operation process, so the bogie frame and the body were built with a flexible body when establishing the dynamics model. The method was: The body and the bogie frame built in the software Pro/E were introduced into the software ANSYS. Their modals were calculated in it and then generated the modal neutral files. Through seamless connection with the ADAMS software, the neutral files were introduced into ADAMS/Rail. Then the rigid-flexible coupling model was established. The simulation research of riding quality was carried out later. The rigid-flexible coupling model is correct though the simulation results contrast with the multi-rigid-body model. Moreover, the results can more accurately reflect the actual dynamic characteristic of the vehicle and they will be a basis for the analysis of the structural fatigue reliability in future work.
