When the high-speed superconducting maglev train is running at high speeds, it generates mechanical vibrations due to air resistance and track structure errors. These vibrations can be classified into high-frequency vibrations and low-frequency vibrations based on their frequencies. Mechanical dampers (hydraulic or pneumatic) between the primary suspension and the secondary suspension can effectively suppress the low-frequency vibrations of the train, but they are difficult to effectively suppress the high-frequency vibrations. High-frequency vibrations can affect passenger experience and pose a threat to the safe operation of the train. To suppress high-frequency vibrations, this paper proposes a method that utilizes the damping force generated by the collector coil, and the core of this method is to use a PWM rectifier to change the power factor angle of the collector current in the collector coil to generate the desired damping force for the train.
