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. To improve the vibration control performance, active or semi-active suspension systems have been applied to this system. Moreover a new technique for obtaining magnetic damping is investigated using distributed power collection system. This paper The characteristic of the Maglev vehicle system was examined by the difference of the input turbulence in this research. Moreover, the effect of the electromagnetic damping on the control of the secondary suspensions was examined.
