Research on the Coupling Vibration of Middle-Speed Maglev Vehicle and Track Beams

The influence of the coupling vibration between the medium-speed maglev vehicle and the elastic bridge is becoming more and more prominent with the increase of vehicle speed, which may cause the vehicle rail crashing and endanger the safety of the vehicle. Therefore, studying and mastering for discipline of movement about suspension system and the elastic bridge track is necessary. In this paper, the electromagnetic field analysis method and the kinetic analysis method are used to mathematically analyze the magnetic field, and the single electromagnet suspension system model is established. Considering the mutual influence between the vehicle and the track under active control, the response of the electromagnetic suspension system is observed, the main parameters of the track and the intrinsic influence on the system vibration is analyzed, and the theoretical analysis is verified by numerical simulation. These results provide the theoretical basis for further research on the vibration of the maglev system.
