SEISMIC ISOLATION DEVICE DAMPER, SEISMIC ISOLATION DEVICE AND SEISMIC ISOLATION DEVICE DAMPER MANUFACTURING METHOD
To provide a hysteresis type damper, made of a general-purpose plate or rod member having a uniform cross-sectional shape normal to a length direction, which prevents an elastoplastic member, having the cross-sectional shape and constituting the damper, from excessively locally deforming and appropriately disperses plastic deformation to absorb vibration energy throughout the entire damper.SOLUTION: A damper 1 is made of a rod-like or plate-like elastoplastic member having a uniform cross-sectional shape normal to a length direction. The damper has a pair of straight parallel line sections 12 and a bent section 11 formed by bending the elastoplastic member to connect one end of each straight parallel line section 12. A ratio of Vickers hardness of the bent section 11 to Vickers hardness of the straight parallel line section 12 is 1.05 or less.SELECTED DRAWING: Figure 1
【課題】長さ方向に直交する断面の形状が均一である汎用的な板材や丸棒材で構成する履歴型ダンパーにおいて、ダンパーを構成する上記形状の弾塑性部材が局所的に過剰に変形することを防いで振動エネルギーを吸収するための塑性変形をダンパー全体に適切に分散すること。【解決手段】長さ方向に直交する断面の形状が均一な棒状又は板状の弾塑性部材からなり、一対の平行な直線部１２と、弾塑性部材が折り曲げられていることによって各々の直線部１２の一方の端部間を結んでいる湾曲部１１によって構成されていて、湾曲部１１のビッカース硬さの直線部１２のビッカース硬さに対する比が１．０５以下である、ダンパー１とする。【選択図】図１
