Popis: Compared ith the traditional wheel-rail train, the maglev train is more vulnerable to lightning strikes due to the lack of contact net protection. In severe cases, it will cause damage to the vehicle-mounted equipment and affect the safety of the train. In order to analyze the indirect effect of lightning on maglev train, the 3D model of maglev train is established. The transmissionline matrix method in CST is used to study the coupling law of cable type, distribution and length of cables under lightning strike. The simulation results show that different types of cables have different coupling characteristics, and the induced current on the shielded cable and the shielded cable is obviously different. With the increase of the distance between the unshielded cable and the bottom of the vehicle and the length of the cable, the induced current of the unshielded cable increases. This method can effectively simulate the indirect effects of the lightning strike on the maglev train, and provides a basis for further research on the protection of the indirect effects of the maglev train.
