Dynamical Vehicle-Guideway Coupling Emulation Model Of Maglev Train System

The history of transportation is the development of the speed of traffic implement. Important progress in the field of high-speed-train has been achieved in such countries as Germany, Japan, France, etc. The developed countries headed by Germany and Japan began to develop maglev-train technology in a more cost-effective manner in the seventies of last century and built test lines. Our country built and operated the first high-speed commerce magnetic railway in the world in January of 2003, too.The horizontal and vertical design parameters have important influence on line-location, construction, project investment, operation expenses, comfortableness and traffic safety, etc. The purpose of suspension system design of Maglev-train is to improve the passenger's comfortableness on the seat. The magnetic railway is generally supported. In order to reduce the fabrication cost, the supported construction should be made comparatively slim and gracefully, which makes vehicle-bridge's coupling effect of maglev-system particularly conspicuous. So in order to analysis the impact of different alignment on the comfort index, we should establish a dynamic model to make a car-guideway coupling emulation.Based on the analysis to the vehicle and guideway sub-systems of Shanghai Maglev- demonstration line, a series of model for carbody, suspend shelf, suspend and guide electro-magnet were set up in this thesis. Each component of those sub-system were mechanically analyzed. Corresponding to the Shanghai Maglev- demonstration line, the lateral and vertical irritation models of the curve guideway were established. Based on the analysis to magnetic force in the curve, a magnetism rail relation model using equivalent suspend rigidity and dampness is adopt. It sets up the system of coordinates of every part of car body on the curve, and utilizes the dynamics principle of many rigid bodies to derive the vehicle curve dynamics equation.This thesis has analyzed definite methods and principles of the alignment design parameter of horizontal and vertical profile. According to these methods and principles, it calculates minimum horizontal curve radius, minimum to relax...
