Maglev train is suspended through the surrounding track, which overcomes many
disadvantages caused by the direct contact between the wheel and rail of
traditional vehicles, such as excessive friction. It has the advantages of high speed,
comfortable riding, less maintenance, strong climbing ability, and so on. However,
when the train is running at high speed, it will be subjected to a strong unsteady
aerodynamic load. The violent disturbance of aerodynamic load will inevitably
lead to the corresponding feedback of electromagnetic force and the change of
the suspension gap, which will affect the stability and safety of the train.
