ATTENUATION DEVICE AND VIBRATION CONTROL STRUCTURE
PROBLEM TO BE SOLVED: To provide an attenuation device and a vibration control structure, capable of suppressing vibration regardless of input level of external force and preventing performance deterioration from occurring.SOLUTION: An attenuation device 1 includes: an elastic member 2 formed into a whole annular shape from a long plate-like elastic material 2A, and laminated in a multi-layer manner through a gap S in a radial direction; and a viscoelastic member 3 comprising a viscoelastic material 3A inserted into the gap S of the elastic member 2, and bonded to the inner and outer elastic materials 2A opposite to each other in the radial direction. The curvature of the elastic member 2 is changed by external force, the viscoelastic member 3 deforms with relative displacement occurring between the inner and outer elastic materials 2A, and thereby attenuation force due to internal viscosity of the viscoelastic member 3 is exhibited.SELECTED DRAWING: Figure 1
【課題】外力の入力レベルに係わらずに振動を抑制するとともに性能劣化を招きにくくすることができる減衰装置及び制振構造を提供する。【解決手段】減衰装置１は、長尺板状の弾性材料２Ａから全体環状に形成されるとともに径方向に隙間Ｓを介して複数層に重ねられた弾性部材２と、弾性部材２の隙間Ｓに介挿される粘弾性材料３Ａからなり径方向に対向する内外の弾性材料２Ａに接着される粘弾性部材３と、を備え、外部からの力によって弾性部材２の曲率が変化し、内外の弾性材料２Ａ間に生じる相対変位に伴って粘弾性部材３が変形することで、粘弾性部材３の内部粘性による減衰力を発揮する。【選択図】図１
