• Vertical vibrations
• Virtual prototype models

In order to reveal the dynamic characteristics of urban-rail magnetic levitation vehicle with five bogies, a virtual prototype model of the vehicle is established with software Catia and ADAMS after a reasonable simplification. Then, a dynamic simulation of the model is carried out in two different operating conditions. The results indicate that, when the vehicle is statically levitated, the carriage body vibrates in lateral, longitudinal and especially vertical directions. Moreover, by analyzing the vertical vibration parameters, it is found that the vehicle is of good ride comfort. The proposed model is proved correct by the consistency of simulated results with the calculated ones when the vehicle goes through a R70m curve.
