Based on the foundation of the virtual prototype model of the medium-speed maglev train, using the mechanical dynamics and kinematics analysis software ADAMS, this paper expatiates on the following things. Firstly, it analyses the decouple of single magnetic bogie by the simulation and experimentation; secondly, adds the magnetic levitation control system to the single magnetic bogie model and simulates; thirdly, by simulating the motion of the train running on the different type of guideway, analyses the state of the train on the ramp and crankle;in the end ,this paper does a further research on how the magnetic levitation control system and guideway parameters affect the suspending gap when the train runs on the ramp and crankle .
