PENDULUM TYPE VIBRATION ISOLATOR
To provide a pendulum type vibration isolator capable of providing stable damping while keeping a natural frequency low to speedily converge residual vibration.SOLUTION: There is provided a pendulum type vibration isolator comprising a pendulum from which an object of vibration isolation is hung and a damping mechanism which damps vibration of the pendulum, wherein the pendulum comprises a hung material support substrate part, a hung material hung from the hung material support substrate part, and a vibration isolation object support substrate part which supports the object of vibration isolation hung by the hung material, and the damping mechanism comprises a viscous fluid tank which is provided to the vibration isolation object support substrate part and filled with a viscous fluid as a damping material, and a spring body which has one end side fixed directly or indirectly to the hung material support substrate part and the other end side made to abut on a bottom part of the viscous fluid tank.SELECTED DRAWING: Figure 1
【課題】固有振動数を低い周波数に保ちつつ、安定した減衰を与えて、残留振動を速やかに収束させることができる振子型防振装置を提供する。【解決手段】防振対象物を吊り下げた振子と、前記振子の振動を減衰させる減衰機構とを具備した振子型防振装置であって、前記振子は、吊り材支持基板部と、当該吊り材支持基板部から吊り下げられた吊り材と、当該吊り材によって吊り下げられ前記防振対象物を支持する防振対象物支持基板部とを具備し、前記減衰機構は、前記防振対象物支持基板部に設けられ減衰材である粘性流体を充填した粘性流体槽と、一端側が前記吊り材支持基板部に対して直接又は間接的に固定され他端側が前記粘性流体槽の底部に当接されたばね体とを具備している。【選択図】 図１
