外文摘要：The quench condition as an extreme operating condition is rarely considered in the mathematical model, but is of great significance to preventing train accidents in advance. In this paper, a closed-loop operational model for the superconducting magnet aboard the vehicle was developed, and comprehensive equivalent circuit equations for the magnetic/rail system were derived, taking into account the magnetic levitation system. The study focused on the current flowing through the superconducting coil and the variations in dynamic magnetic force within the magnetic levitation system during the loss-of-superconductivity process. Secondly, multi-body dynamic mathematical model with 55-degree of freedom (DOF) is established to simulate a more realistic operating condition of the train, and its reliability is validated by SIMPACK/MATLAB co-simulation. Finally, the electro-magnetic interactions with magnet quenched are input into the dynamic model as external disturbances to investigate the vehicle dynamic characteristics of superconducting EDS train. The results indicate that, the quench suspension frame will move laterally and vertically towards the quench side when the SCM is quenched. The lateral displacement speed of the quench magnet is large, and the suspension vehicle will first touch the side wall of the track to cause suspension instability.
