TUNED MASS DAMPER
PROBLEM TO BE SOLVED: To prevent a rocking vibration of a mass body of a tuned mass damper that might occur when an elastic member integrally formed with attenuation member is applied in the tuned mass damper.SOLUTION: This invention relates to a tuned mass damper in which a mass body arranged at either above or below an object of which vibration is controlled is vibrated up and down in synchronization with an upward or downward vibration of the object of which vibration is controlled, thus suppressing the upward or downward vibration of the object of which vibration is controlled. At least three first elastic members are inserted side-by-side to each other between the mass body and the object of which vibration is controlled to support the mass body, there are provided at least one second elastic member inserted side-by-side with the first elastic member between the mass body and the object of which vibration is controlled and supporting the mass body and an attenuation member integrally formed with the second elastic member while being arranged side by side with the second elastic member. A distance in a horizontal direction among the three first elastic members and the center of gravity of the mass body is larger than a distance in a horizontal direction between the second elastic member and the position of the center of gravity.SELECTED DRAWING: Figure 2
【課題】減衰部材が一体化された弾性部材をチューンドマスダンパーに用いることで起こり得る同ダンパーの質量体のロッキング振動を防ぐ。【解決手段】制振対象物の上方又は下方に配置された質量体が、前記制振対象物の上下振動に同調して上下振動することにより、前記制振対象物の前記上下振動を抑制するチューンドマスダンパーである。前記質量体と前記制振対象物との間に互いに並列に介挿されて前記質量体を支持する少なくとも３つの第１弾性部材と、前記質量体と前記制振対象物との間に前記第１弾性部材と並列に介挿されて前記質量体を支持する少なくとも１つの第２弾性部材と、前記第２弾性部材に並列に設けられつつ前記第２弾性部材に一体化された減衰部材と、を有する。前記３つの第１弾性部材と前記質量体の重心の位置との水平方向の距離は、前記第２弾性部材と前記重心の位置との水平方向の距離よりも大きい。【選択図】図２
