Study on Dynamic Characteristics of Maglev System with Single Maglev Frame and Multi-controller Coupling

The simulation method of maglev system is given to realize elastic and multi-controller coupling using FEA softwareinteracting with simulation software of control system. With the method, the mechanical decoupling is studied for the elastic maglev frame. Inthe simulation software of control system, the dynamic model of the rigid components is built as well as the feedback model of maglevcontroller. Also built with finite element technology is the model of elastic suspension frame. All the FEA processes of motion response of theelastic maglev frame are realized through programming by secondary development language. The interface of FEA program accessed bysimulation program is realized by C language programming, so as to realize the simulation of the whole maglev system. The simulationprocess proves that the coupling effect between the maglev controllers could be removed of weakened with elastic maglev frame.
