Abstract: Through building single magnet model with ANSYS, according to the highspeed maglev vehicle in Shanghai, the magnetic field distribution under standard working conditions and that how the design parameters changing affected the levitation force were analyzed. The academic basis for optimal design of magnet and stability of levitation control were offered. Finally, by the analysis of the combining magnets model, the accuracy of the analysis of the single magnet model was proved.
Key words: electromagnetic suspension (EMS); electrodynamic suspension (EDS); single magnet; levitation force
