To provide a vibration suppression device of a railway vehicle capable of suppressing reversed excitation.SOLUTION: A vibration suppression device of a railway vehicle (1) includes a sensor (4), an actuator (5), and a control device (6). The sensor (4) detects vibration acceleration in a right and left direction of a vehicle body (3). The actuator (5) applies thrust to the vehicle body (3) so as to attenuate the vibration acceleration of the vehicle body (3). The control device (6) acquires the vibration acceleration from the sensor (4) and transmits a signal of the thrust to the actuator (5). The control device (6) calculates required thrust in accordance with the vibration acceleration. The control device (6) generates a signal of the thrust which is restricted within a first range between a positive first maximum value and a negative first minimum value by performing the saturation operation of the required thrust. The control device (6) generates a signal of the thrust by which the required thrust is converged to zero when the required thrust exceeds a second range between a positive second maximum value larger than the first maximum value and a negative second minimum value smaller than the first minimum value.SELECTED DRAWING: Figure 1

    【課題】逆加振を抑制することができる鉄道車両の動揺抑制装置を提供する。【解決手段】鉄道車両(1)の動揺抑制装置は、センサ(4)と、アクチュエータ(5)と、制御装置(6)と、を備える。センサ(4)は、車体(3)の左右方向の振動加速度を検知する。アクチュエータ(5)は、車体(3)の振動加速度が減衰するように車体(3)に推力を与える。制御装置(6)は、センサ(4)から振動加速度を取得し、アクチュエータ(5)に推力の信号を送出する。ここで、制御装置(6)は、振動加速度に応じて要求推力を算出する。制御装置(6)は、要求推力を飽和演算することにより、正の第1最大値と負の第1最小値との間の第1範囲に制限した推力の信号を生成する。制御装置(6)は、要求推力が第1最大値よりも大きい正の第2最大値と第1最小値よりも小さい負の第2最小値との間の第2範囲を超える場合、ゼロに収束するような推力の信号を生成する。【選択図】図1
