Magnetically levitated (MAGLEV) vehicle systems have been studied for use in future high speed transportation. It is especially important to investigate dynamic characteristics for running stability, safety and ride quality at high speed. This paper concerns dynamic characteristics of repulsive-type MAGLEV systems using electrodynamic suspension (EDS). Since the electrodynamic suspension is inherently stable but of low damping character, mechanical resonance is liable to occur in levitated body motion. Moreover, since the system uses conductive eddy current in coils or sheets on a guideway, the repulsive force is influenced by magnetic fields generated by adjacent magnets located in the longitudinal direction. In this study we investigate magnetically couped vibration between two independent levitated bodies running above an aluminum plate.
