초록

In this study, overturning safety for a tilting train has been evaluated. In the tilting train, the overturning safety is one of the most important factors because the carbody inclines inward a curve during curve negotiation. Dynamic analysis considering unbalanced lateral acceleration and carbody tilting has been carried out and the overturning safety for the tilting train has been evaluated according to height of CG of carbody. From these studies, the overturning safety for the tilting train under unbalanced lateral acceleration of $2m/s^2$ was superior to the conventional one at the same running speed.
