Effects of Track Irregularities on Dynamic Responses of a Moving Maglev Train 2005-01-0504
In this paper, a study on the effects of track irregularities on the dynamic responses of a magnetically levitated (Maglev) train is presented. The track here is a combination of concrete guideway, rails and ribs. Its irregularities can be due to the flexibility and the unevenness of the track. The Maglev train is modeled as a system with six degrees of freedom. The fundamental dynamic characteristics of each components of the Maglev train are obtained from the detailed finite element analysis. It is the goal of the paper to identify the elements of the track irregularities that have major effect on the dynamic responses of the moving Maglev train. The results may lead to a better track design that induces less vertical displacement and acceleration of the Maglev train, which in turn can make the control of the train easier.
