• In designing electromagnetic levitation (EML) vehicles as a means of high speed ground transit, it is important to explore the dynamic interactions between a long train of EML vehicles and their guaideways. For the numerical analysis of this system, the computer simulation program has been developed, in which vehicle equations are fully coupled with guideway equations through distributed suspension forces. Vehicle motion is asumed to consist of heave and pitch of the vehicle body and heave of two trucks. According to the analysis, there is a difference between variations of the vibration of each truck or each vehicle body, especially in a high speed operation, depending on the velocity parameter, the truck intervals and guideway structures. In some cases, the variations of the vertical accelerations and the clearances between magnets and guideway surfaces at the following vehicles tend to increase to about twice those at the preceding one.
