In order to explore the middle-speed adaptability of the rail beams including 25 m Changsha maglev simply-supported girder, the finite element dynamic analysis models for maglev rail beams was established firstly based on the finite element theory, of which the self-oscillation characteristics are analyzed. The dynamic model of middle-speed maglev train with 120 degrees of freedom is set up based on multi-body dynamics theory. Then the maglev train-bridge-controller coupled model is established considering the PID active suspension control as levitation force. Based on the vehicle-bridge-controller coupled model, the vibration responses of the vehicle-bridge system are further studied at middle speed with track beams which are taken as the structure under the rail. The simulation speed ranges from 100 km/h to 180 km/h. Then the vertical vibration responses of bridge and car body are calculated and analyzed.
