Superconducting maglev systems have been developed as high-speed transportation systems.The magnetic-rail relation is an essential link between the maglev vehicle and the track and a crucial factor in ensuring the smooth and safe operation of the vehicle.In this paper, the circuit model based on superconducting maglev principle was used to developed to solve electromagnetic force.The magnetic-rail relation is then performed for the linear spring, nonlinear stiffness and coupling models.According to the dynamic simulations based on the new 200 m straight test line to research applicable conditions and accuracy of the three kinds of magnetic-rail relation models so as to further improve the efficiency of dynamic simulation of superconducting maglev vehicle.
