Recently, the superconducting Maglev is noticed as the next generation high-speed public transportation system. In realization, it is important to improve the ride comfort. Maglev vehicle is composed of lightweight car body and bogie which is mounted on the SCM (superconducting magnets), the cooling device, and etc. The vibration isolation performance degrades, since the ratio of sprung mass is nearly the unsprung mass. In the magnetically levitation system, the magnetic damping between the SCM and ground coils is so small that it can be neglected. Therefore, it is important to adjust the car body - bogie suspension. This study focuses on the reduction of the lateral vibration. In this paper, the vibration characteristic of Maglev vehicle is analyzed. The vibration control system is designed by LQ control theory. Moreover, the case considers the effect of the magnetic damping is investigated.
