Dynamic Response Characteristics of Superconducting EDS Train Considering the Position of Magnet Quenching

In this paper, the dynamic response characteristics of the suspension vehicle system caused by the quenching of superconducting magnets are investigated. Based on the established full-coupled magnetic/rail calculation model of the electric suspension system in the closed-loop operation mode of superconducting magnets, the superconducting magnet quenching at different positions is numerically simulated and analyzed, considering the superposition effect of dynamic electromagnetic force fluctuations and track irregularities. In addition, the moving interval algorithm is adopted to solve the long track line in the dynamic model, which significantly improves the computational efficiency of the model. The results show that the quenching of non-articulated frame magnets has a greater impact on the safety of the suspension vehicle than that of articulated frame magnets. The quenching of the middle magnets has a greater impact on the lateral and vertical dynamic response changes of the suspension vehicle system. The position of the quenched magnet has a significant impact on the safety and dynamic response characteristics of the suspension vehicle.
