Magnetic levitation vehicle, wheel polygon detection and active suppression method and related system

The invention discloses a magnetic levitation vehicle, a wheel polygon detection and active suppression method and a related system. The method comprises the following steps: acquiring data of a wheel out-of-roundness signal, a vibration acceleration signal and a noise signal; importing the wheel out-of-roundness signal into a co-simulation model, and outputting a vibration acceleration signal and a noise signal after simulation; constructing a data set S by using the simulated vibration acceleration signal and noise signal; part of samples in the data set S are randomly selected as a training sample set, the training sample set serves as input of a support vector machine, the support vector machine is trained, and a mapping model of polygon wavelength and amplitude relative vibration noise signal features is established; inputting a to-be-detected sample into the mapping model to obtain a polygon amplitude prediction result; if the polygon amplitude prediction result exceeds a critical threshold value, it is
