Magnetically levitated vehicle, so-called Maglev vehicle, is noticed as the next generation high-speed public transportation system. For the practical use, it is important to improve the ride comfort at high-speed operation. Maglev vehicle is composed of lightweight car bodies and bogies mounted on super-conducting magnets (abbreviated as SCMs) and on-board refrigerating systems. It is rather difficult to design the secondary suspension as a vibration isolation system between the car body and bogie, because the ratio of sprung to un-sprung mass is small and the damping between SCMs and ground coils is very small. In this paper, the modal analysis by using the vehicle model, and the theoretical analysis of the vibration characteristic of the car body and bogie are inspected. Position of damper that is suitable for vibration mode, is evaluated in order to reduce the vibration. Moreover, the vibration control system for the ride comfort improvement is examined and effectiveness is confirmed.
