PROBLEM TO BE SOLVED: To provide a railway vehicle vibration control device capable of removing a drift component from the output of an acceleration sensor without losing a vibration control effect.SOLUTION: A railway vehicle vibration control device V is provided with: an actuator A that can be unloaded during driving of a pump 12 by a motor 15; an acceleration sensor 40 that is installed in a vehicle body B and detects lateral acceleration of the vehicle body B; and a controller C that controls the actuator A on the basis of the acceleration. An offset value for canceling a drift component included in the output value of the acceleration sensor 40 is measured during unloading of the actuator A while driving the motor 15.SELECTED DRAWING: Figure 4
【課題】本発明は、制振効果を損なわずに加速度センサの出力からドリフト成分を取り除ける鉄道車両用制振装置の提供を目的とする。【解決手段】本発明の鉄道車両用制振装置Vは、モータ15でポンプ12を駆動中にアンロード可能なアクチュエータAと、車体Bに設置されて車体Bの左右方向の加速度を検知する加速度センサ40と、加速度に基づいてアクチュエータAを制御するコントローラCとを備え、モータ15を駆動しつつアクチュエータAをアンロード中に、加速度センサ40の出力値に含まれるドリフト成分を打ち消すオフセット値を計測する。【選択図】図4
