This study investigates the dynamic interactions between a vehicle and guideway of a high-speed ground transportation system based on magnetically levitated (maglev) vehicles. 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 numerous degrees of freedom, representing the passenger cabin and primary and secondary suspensions of the vehicle with lumped masses, linear springs and dampings. The Bernoulli-Euler beam equation is utilized to model the characteristics of a flexible guideway. Guideway synthesis is based on a modal analysis method. Computer simulation is performed to investigate the number of vehicle suspension systems that affect the dynamic interactions between a vehicle and a discretely supported guideway. Finally, the various simulations are compared
