Study on Effects of Natural Frequency of a Guideway on Running Behaviour of a Maglev Vehicle

궤도 고유진동수에 따른 자기부상열차 주행특성 연구

Since Maglev vehicle is run over an elevated guideway, the vibrational characteristics of guideway 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 natural frequency ratio of a guideway.
