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.
