To provide a method by which rotational vibrations of a vehicle body are suppressed while structural modifications of the vehicle body and a truck are moderate.SOLUTION: A railway vehicle which has a vehicle body and plural trucks supporting the vehicle body comprises a rotating suppressor device that has at least a pair of first and second flywheels and controls vibrations of the vehicle body. The rotating suppressor device makes the first flywheel and the second flywheel rotate mutually in reverse directions and also makes first and second gimbal shafts rotate mutually in reverse directions, based on detected values of the vehicle body vibration, the first and second gimbal shafts being orthogonalized respectively to rotation axes of the first and second flywheels.SELECTED DRAWING: Figure 2
【課題】車体および台車の構造変更を少なく車体の回転振動を低減する。【解決手段】車体と車体を支持する複数の台車とを備える鉄道車両が、第1のフライホイールと第2のフライホイールとのペアを少なくとも一つ備え車体の振動を制御する回転抑動装置を備える。回転抑動装置が、第1および前記第2のフライホイールを互いに逆方向に回転させ、かつ、車体振動の検出値に基づき第1および第2のフライホイールの回転軸と直交する第1および第2のジンバル軸を互いに逆方向に回転させる。【選択図】 図2
