In Japan, the railway has many curved sections. In future, since the railway will become more complicated and require more speed, the railway vehicle needs to improve its curving ability. The indices of curving performance are wheel-load, lateral wheel-rail force, coefficient of derailment, and extra centrifugal acceleration. The wheel-load and lateral wheel-rail force are closely related to derailment. Therefore, it is effective to control them in order to balance each wheel-load and to reduce lateral wheel-rail force. In this study, the control method of sudden change of each wheel-load in the curved section particularly in the transition curve is presented. The railway vehicle is modeled as a multibody by using mechanical analysis software, such as ADAMS and DADS. And the curving dynamics of wheels, truck and cars is analyzed by the numerical calculation. Furthermore, motion control using air suspension is attempted.
