ROTATIONAL INERTIA MASS DAMPER
To provide a rotational inertia mass damper which can maintain a flow rate of a hydraulic oil as originally designed even in use over a long time and achieve damping performance properly.SOLUTION: A rotational inertia mass damper includes: a damper body 2 including a cylinder 20 which is filled with a viscous fluid 21; a piston 51 which partitions the interior of the cylinder 20 into a pair of pressure chambers and moves; a movable rod 5 connected to the piston 51; an operation passage 31 for moving the viscous fluid 21 from a high pressure side pressure chamber 22 to a low pressure side pressure chamber 22; a hydraulic motor 30 which is provided at the operation passage 31 and generates rotational motion; a rotary weight 60 which is provided with rotational force of the hydraulic motor 30; a drain circuit which recovers the viscous fluid from the hydraulic motor; and a pair of return passages 34 which communicates with the drain circuit 33 and connects the high pressure side operation passage 31 with the low pressure side operation passage 31 through a check valve 32.SELECTED DRAWING: Figure 1
【課題】経時的な使用においても作動油の流量を当初設計通りに維持することが可能であり、減衰性能を適切に発揮することが可能な回転慣性質量ダンパを提供する。【解決手段】内部に粘性流体２１が充填されたシリンダ２０を備えるダンパ本体２と、前記シリンダ２０内を一対の圧力室に区画し移動するピストン５１と、前記ピストン５１に連結された可動ロッド５と、高圧力側の圧力室２２から低圧側の圧力室２２に前記粘性流体２１を移動させる作動流路３１と、前記作動流路３１に設けられ、回転運動を生成する油圧モータ３０と、前記油圧モータ３０の回転力が与えられる回転錘６０と、前記油圧モータから前記粘性流体を回収するドレン回路と、前記ドレン回路３３と連通していると共に、チェック弁３２を介して高圧側の作動流路３１と低圧側の作動流路３１を接続する一対の戻し通路３４と、を備える。【選択図】 図１
