Static Levitation Stability Researches And Simulation Of Maglev

As a new type of conveyances, Maglev Vehicle has aroused more and more attention because of its high velocity, comfortable riding, few pollution and low noise.In order to speed the procession of our country's own manufacture of MAGLEV vehicle, and to shorten the distance between our country and other developed countries, such as Germany and Japan, we should know more their technology and assimilate their advantage. It's a short-cut to the destination.This paper is part of the reliability and application evaluation of dynamical simulation soft of the MAGLEV. The main work is focused on analysis and simulation of the static levitation stability of MAGLEV vehicle. The structure of modern MAGLEVvehicle is modularized, which is made the separate control be used very common in MAGLEV. So it gives very important meaning to research on single magnetic suspension system.Though the solution of the convergence mass or single force moving on elastic beam, but the work of simulating the satatic levitation of the MAGLEV in elastic beam is never or less done. In the paper, the single magnetic, elastic beam and carbody coupling model is built through control system studied in the former phase. And analyse the facter which affects the vehicle/guideway coupling vibration. On the base of these, Using the shanghai MAGLEV train as prototype, the integrity of the train model is set up to analyze the static levitation instability of the MAGLEV and the solution, considering the flexibility of guidway and the control system. At the same time, the theoretical analysis is done in this paper. The method that synthesize mechanism system and control system just indicate the advanced field of the vehicle research.Through the simulation and the theory analysis of this paper, some conclusions are obtained. It has made a solid foundation for the further understanding and research of the system.
