Eddy Current Effects on the Guiding System of High-Speed Maglev Train

During the operation of high-speed maglev train, the eddy current is induced in the rail and the force of the guide electromagnet imposing on the rail will change notable, which would affect the adjustment of parameters of the guide controller. In this paper, a mathematical three-dimensional model of eddy currents of high-speed maglev train is established, and the finite element simulation is carried out by Ansoft Maxwell software. The changing rule of the guiding force and distribution of the eddy current are analyzed under different operating velocity of high-speed maglev train. The relationship is discussed among the velocity, air gap length, polar area and guiding force. This research will provide theoretical support for the optimal design of the guidance structure and guidance controller for high-speed maglev train.
