Modeling and Simulation of High-speed Maglev Vehicle/Guideway/Bridge Coupling System

In this paper, vehicle, guideway and bridge are studied as a whole body. The vehicle is modeled as a multi-body system connected by springs and dampers. The motion equations of vehicle are built by means of energy method, while guideway and bridge differential equations are deduced by dynamic finite element method. They are connected through mag-net/guideway relationship and guideway/bridge relationship, so that the coupling dynamics system is established. The corresponding dynamics simulation programs are compiled base on the above model. Using it, the dynamic responses of vehicle, guideway and bridge are analyzed under sinusoidal irregularity.
