(鉄道車両用アクティブサスペンション・世界初の実用化への道のり)

抄録

In railway vehicles technologies, to provide a comfortable ride quality is an eternal challenge. However, a mechanical suspension design has the technical limits to improve the ride quality. To break through this issue, we have developed the active suspension from 1990s and as the result of these studies, the pneumatic active suspension as the 1^st generation and the electro mechanical active suspension as the 2^nd generation were put into the practical use on JR EAST Shinkansen and the conventional line express trains in Japan. In this paper, the author reports the configuration and development history of the active suspension in Japan.
