VIBRATION SUPPRESSION DEVICE
To provide a vibration suppression device which can design an inertia connection element easily.SOLUTION: A vibration suppression device includes: an inertia connection mechanism having a nut which is fixed to a vibration suppression object and may move integrally with vibration of the vibration suppression object and a screw shaft which extends in a linear direction, is rotatably supported by a base part in a state that movement in the linear direction is restricted, is screw-joined to the nut, and may rotate in conjunction with movement of the nut; a rotation amount amplification mechanism having an input shaft which rotates in conjunction with rotation of the screw shaft, an output shaft coaxially disposed with the input shaft, and an amplification part which amplifies a rotation amount of the input shaft to transmit the rotation to the output shaft; and a damping mechanism which follows rotation of the output shaft and absorbs kinetic energy.SELECTED DRAWING: Figure 1
【課題】慣性接続要素を容易に設計することが可能な制振装置を提供する。【解決手段】制振装置は、制震対象物に固定され制震対象物の振動と一体で移動可能なナットと、直線方向に延び直線方向への移動が規制された状態でベース部に回転可能に支持されナットとネジ接合されてナットの移動に伴って回転可能なネジ軸と、を有する慣性接続機構と、ネジ軸の回転に伴って回転する入力軸と、入力軸と同軸に配置される出力軸と、入力軸の回転量を増幅して出力軸に伝達する増幅部と、を有する回転量増幅機構と、出力軸の回転に従動して運動エネルギーを吸収する減衰機構とを備える。【選択図】図１
