英文摘要：

In this paper, the maglev vehicle/guideway dynamic model is established based on the EMS maglev vehicle and the elevated-guideway technology, the PSD model for guideway irregularities is discussed, and the separated iterative procedure and its corresponding numerical algorithm are applied in simulations. The effect of random irregularity on dynamic characteristics of the maglev system is studied numerically, and the random responses of the vehicle and the guideway are analyzed. Finally the random vibration characteristics of the vehicle/guideway system are obtained. It is on this basis that control suggestions are proposed for guideway irregularity in maglev.
