摘要： A railway vehicle vibration damping device having at least two vibration suppression force generating sources interposed between a bogie and a vehicle body of a railway vehicle extracts from a transverse direction velocity of the vehicle body a frequency component at or above a frequency of a centrifugal acceleration of the vehicle body, and calculates a high frequency vibration suppression force on the basis thereof. When the railway vehicle travels in a curve section, at least a part of the vibration suppression force generating sources is caused to output the high frequency vibration suppression force, and the remaining vibration suppression force generating sources are caused to function as passive dampers. As a result, passenger comfort in the railway vehicle during travel in a curve section is improved.

摘要： A railway vehicle damping device comprises at least two front side actuators interposed between a front bogie and a vehicle body of a railway vehicle, and at least two rear side actuators interposed between a rear bogie and the vehicle body of the railway vehicle, and suppresses vibration in a yaw direction of the vehicle body using a yaw suppression force generated by the actuators. After determining that the railway vehicle is traveling in a curve section, a control device causes at least one of the front side actuators and at least one of the rear side actuators to generate a yaw suppression force, and causes all of the remaining actuators to function as passive dampers. As a result, passenger comfort in the railway vehicle during travel in the curve section is improved.
