The purpose of this paper is to study the dynamic interactions between the vehicle and guideway of a high speed ground transportation system based on magnetically levitated (maglev) vehicles, and the guideway is assumed to be made up of identical simply supported beams with single spans and rigid supports. The vehicle is considered to be two-dimensional, with four degrees of freedom, representing passenger cabin mass and the primary and secondary suspensions of the vehicle with the lumped masses, linear springs and dampings. The Bernoulli-Euler beam equation is used to model the characteristics of a flexible guideway, and the guideway synthesis is based on a modal analysis method. Computer simulation has also been performed in this study to investigate the influences of the locations of mass of center of passenger cabin and the asymmetrical suspension characteristics of in the suspension systems of the vehicle on vehicle/guideway dynamic interactions.
