VIBRATION PREVENTION DEVICE OF STRUCTURE
To provide a vibration prevention device of a structure capable of setting an actual mass of a rotary mass to a relatively large value, without enlarging a flow conversion mechanism.SOLUTION: A cylinder 2 filled with hydraulic fluid HF is connected to a first portion CS, and a piston 3 provided slidably in an axial direction in the cylinder 2 sections the cylinder 2 into a first fluid chamber 2d and a second fluid chamber 2e, and is connected to a second portion FB. The hydraulic fluid HF bypasses the piston 3, and flows into a communication passage 5 communicating between the first and second fluid chambers 2d, 2e, and then flow of the hydraulic fluid HF in the communication passage 5 is converted into rotation power of a rotor by a flow conversion mechanism M. A rotary mass 15 is rotatably supported at a support part 35 fixed to a predetermined portion CS, and the rotation power of the rotor is transmitted to the rotary mass 15 in a state of being decelerated by a speed reduction mechanism 31.SELECTED DRAWING: Figure 1
【課題】流動変換機構を大型化することなく、回転マスの実質量を比較的大きな値に設定することが可能になる構造物の振動抑制装置を提供する。【解決手段】作動流体ＨＦが充填されたシリンダ２が、第１部位ＣＳに連結され、シリンダ２内に軸線方向に摺動自在に設けられたピストン３が、シリンダ２内を第１流体室２ｄと第２流体室２ｅに区画するとともに、第２部位ＦＢに連結される。ピストン３をバイパスし、第１及び第２流体室２ｄ、２ｅに連通する連通路５に、作動流体ＨＦが充填され、連通路５内の作動流体ＨＦの流動が、流動変換機構Ｍにより回転体の回転動力に変換される。所定部位ＣＳに固定される支持部３５に、回転マス１５が回転自在に支持され、回転体の回転動力が、減速機構３１により減速した状態で回転マス１５に伝達される。【選択図】図１
