Study on Effects of Damping of a Guideway on Running Behaviour of a Maglev Vehicle

Since Maglev vehicle is run over an elevated guideway, the structural properties of guideways affect the running behavior of the vehicle and guideway. The design of a guideway has a strong effect on the costs of constructing guideways, therefore optimized design of the guideway satisfying running performance is needed for the commercialization of the Maglev vehicle. With an analysis program for dynamics of Maglev vehicles, the dynamic responses of the Maglev vehicle with electromagnet suspension are numerically analyzed according to changes in fundamental modal damping ratio of a guideway.
