Background technique

High-speed train is a development direction of modern high-tech rail transit. After the high-speed rail technology of wheel-rail technology achieves a speed of 400KM/h, there is no higher development space due to the reduction of friction between wheels and rails. The way to achieve higher speed train speed can also adopt the magnetic levitation system, which realizes the contactless suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to pull the train. At present, the maglev train system can be divided into two directions, namely the constant-conducting magnetic (EMS) used in Germany and the superconducting magnetic repulsion (EDS) train used in Japan. The current highest speed is the Japanese Superconducting Magnetic Rejection (EDS) train, which has reached 600KM/h, and this speed has not yet been truly commercialized.
