Abstract
The superconducting Maglev system, which makes use of the non-contacting support, becomes attractive for further development. The running stability at low speed in straight line and curved line as well as riding comfort in levitated running are focused to be topics in the viewpoint of vehicle dynamics. Maglev vehicle is composed of lightweight car bodies and bogies which is mounted on the SCMs (superconducting magnets), the cooling device, etc. The vibration isolation performance degrades, since the ratio of sprung mass is nearly the unsprung mass. In the magnetically levitation system, the electromagnetic damping between the SCMs and ground coils is so small. Therefore, it is important to adjust the secondary suspension between car body and bogie. This paper focuses on the reduction of the lateral vibration of Maglev vehicle using the vibration control system designed by LQ control theory. Moreover, the case considering the effect of the electromagnetic damping is investigated.
