VIBRATION SUPPRESSION DEVICE OF STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration suppression device which realizes a single device having multiple vibration suppression characteristics which can be alternatively selected and thereby can properly inhibit vibration of a structure.SOLUTION: A piston 3 is provided in a cylinder 2 so as to slide in an axial direction and partitions the interior of the cylinder 2 into a first fluid chamber 2d and a second fluid chamber 2e. A working fluid HF fills the first and second fluid chambers 2d, 2e. A first communication passage 7 bypasses the piston 3, communicates with the first and second fluid chambers 2d, 2e, and is opened and closed by a first opening/closing valve 8. A power conversion mechanism 9 converts flow of the working fluid HF in the first communication passage 7 into rotary motion and transmits the rotary motion to a rotary mass 15 which is freely rotatable. A second communication passage 16 provided in parallel to the first communication passage 7 bypasses the piston 3, communicates with the first and second fluid chambers 2d, 2e, and is opened and closed by a second opening/closing valve 17.SELECTED DRAWING: Figure 1
【課題】択一的に選択可能な複数の振動抑制特性を有する単一の装置を実現でき、それにより、構造物の振動を適切に抑制することができる振動抑制装置を提供する。【解決手段】ピストン３が、シリンダ２内に軸線方向に摺動自在に設けられ、シリンダ２内を、第１流体室２ｄと第２流体室２ｅに区画している。作動流体ＨＦが第１及び第２流体室２ｄ、２ｅに充填され、第１連通路７が、ピストン３をバイパスし、第１及び第２流体室２ｄ、２ｅに連通しており、第１開閉弁８で開閉される。動力変換機構９が、第１連通路７における作動流体ＨＦの流動を回転運動に変換し、回転自在の回転マス１５に伝達する。第１連通路７と並列に設けられた第２連通路１６が、ピストン３をバイパスし、第１及び第２流体室２ｄ、２ｅに連通しており、第２開閉弁１７で開閉される。【選択図】図１
