DAMPER STRUCTURE AND METHOD FOR MANUFACTURING DAMPER
PROBLEM TO BE SOLVED: To provide a damper structure which can be manufactured at a low cost while securing stable energy absorption performance.SOLUTION: A damper structure 1 according to this invention is installed in an axial force member 2 on which a tension load Pt or a compression load Pc acts, and includes an energy absorbing part 3 provided in a part of the axial force member 2 in an axial direction Z. In the energy absorbing part 3, a plurality of cutouts 4 cut at plural portions in a circumferential direction X and a bent part 5 protruded to a surface outer direction Y between the plurality of cutouts 4 are formed on a side plate 31 having an approximately circular cross section. When the tension load Pt or the compression load Pc acts on the axial force member 2, the energy absorbing part 3 is deformed to expand and contract in the axial direction Z at the bent part 5.SELECTED DRAWING: Figure 7
【課題】安定したエネルギー吸収性能を確保しながら低廉な製造コストで製造することのできるダンパー構造を提供する。【解決手段】本発明を適用したダンパー構造１は、引張荷重Ｐｔ又は圧縮荷重Ｐｃが作用する軸力部材２に設けられるものであり、軸力部材２の軸方向Ｚの一部に設けられるエネルギー吸収部３を備える。エネルギー吸収部３は、断面略円形状に形成された側板３１に、周方向Ｘの複数箇所で切り欠かれた複数の切欠部４と、複数の切欠部４の間で面外方向Ｙに突出させた折曲部５とが形成されて、引張荷重Ｐｔ又は圧縮荷重Ｐｃが軸力部材２に作用したときに、折曲部５で軸方向Ｚに伸縮変形するものとなる。【選択図】図７
