Abstract
Railway vehicles traveling on curved track with cant are affected by inertial force. This study constructs local coordinates movimg along curved tracks with cant on absolute coordinates to express mathematical model of the motion for the railway bogie. This study also uses the model of the bogie with coupling motion between the roll angle of bogies and the yaw angle of wheelsets due to link structure. The traveling characteristics of bogies are investigated by numerical simulations. This study investigates the effects of curve radius of track and cant angle on the traveling stability and the critical speed of hunting motion through time historical responses and eigenvalue analysis.
