EDDY CURRENT TYPE DAMPER
To provide an eddy current type damper in which a damper that may suppress vibration of a structure can be properly and easily installed.SOLUTION: An eddy current type damper which is provided together with a V type brace 2 in a frame formed of poles PL, PR and beams BU, BD of a structure S for suppressing vibration of the structure S comprises: a magnet holder 3 which is provided on the tip of the V type brace 2 and horizontally extends by a prescribed length; a facing extension body 4 which faces the magnet holder 3 with an interval of a prescribed distance in the vertical direction; and a plurality of permanent magnets 5 which are attached to the magnet holder 3, face the facing extension body 4 with an interval and are arranged along the longitudinal direction of the magnet holder 3. The facing extension body 4 is configured such that the eddy current for generating resistance force that prevents the movement is generated when the magnet holder 3 and the facing extension body 4 relatively move on the surface facing the plurality of permanent magnets 5 with an interval.SELECTED DRAWING: Figure 1
【課題】構造物の振動を抑制し得るダンパを、適切にかつ容易に設置することができる渦電流式ダンパを提供する。【解決手段】構造物Ｓの柱ＰＬ、ＰＲ及び梁ＢＵ、ＢＤによる架構に∨型ブレース２とともに設けられ、構造物Ｓの振動を抑制するための渦電流式ダンパであって、∨型ブレース２の先端部に設けられ、水平に所定長さ延びる磁石ホルダ３と、磁石ホルダ３に対し上下方向に所定距離を隔てて対向する対向延設体４と、磁石ホルダ３に取り付けられ、対向延設体４に間隔を隔てて対向しかつ磁石ホルダ３の長さ方向に沿って配置された複数の永久磁石５と、を備え、対向延設体４は、複数の永久磁石５と間隔を隔てて対向する面において、磁石ホルダ３と対向延設体４が相対的に移動する際に、その移動を妨げる抵抗力を発生させるための渦電流が生じるように構成されている。【選択図】図１
