PROBLEM TO BE SOLVED: To provide a railroad car vibration damping device capable of improving ride comfort when traveling along a transition curved section without sacrificing cost and mountability to a railroad car.SOLUTION: A railroad car vibration damping device 1 is provided with: actuators A which are interposed between a railroad car body B and a bogie T, and are capable of exerting a control force; and a controller C which determines a target control force Fref for suppressing vibrations in the car body B on the basis of the lateral acceleration α of the car body B. The controller C is configured by comprising: a band-pass filter 413 which extracts a low-frequency control force Flow that is a frequency component lower than the resonant frequency of the car body B; and a correction unit 414 which corrects a target control force Frefon the basis of the low-frequency control force Flow.SELECTED DRAWING: Figure 4

    【課題】コストと鉄道車両への搭載性を損なわずに緩和曲線区間走行時の乗心地を向上できる鉄道車両用制振装置の提供である。【解決手段】本発明の鉄道車両用制振装置1は、鉄道車両の車体Bと台車Tとの間に介装されて制御力を発揮可能なアクチュエータAと、車体Bの横方向加速度αに基づいて車体Bの振動を抑制する目標制御力Frefを求めるコントローラCとを備え、コントローラCが車体Bの共振周波数よりも低い周波数成分である低周波制御力Flowを抽出するバンドパスフィルタ413と、低周波制御力Flowに基づいて目標制御力Fref*を補正する補正部414とを有して構成される。【選択図】図4
