DAMPER DEVICE AND DAMPING METHOD
PROBLEM TO BE SOLVED: To make it possible to attenuate and thereby damp an oscillation of a damping object in all directions of horizontal two dimensions.SOLUTION: A damper device (dynamic vibration absorber 10) installed in a seismic isolation object 1 and damping an oscillation of the seismic isolation object, comprises: a mass body 11 including a curved part 16 having a curvature radius at each position in a circumferential direction and a conductor part 17 configured from a conductor; a mass body support 12 provided on the seismic isolation object 1 and supporting the mass body 11 from below so that the mass body can oscillate; and magnets 13 provided in the seismic isolation object by magnet supports 14 so that the conductor part 17 passes through a magnetic flux when the mass body 11 oscillates.SELECTED DRAWING: Figure 2
【課題】制振対象の水平２次元の全方向に対する揺動を減衰して制振できること。【解決手段】免震対象物１に設置されて、この免震対象物の揺動を制振する制振装置（動吸振器１０）において、周方向各位置に曲率半径を有する曲面部１６、及び導電体にて構成された導体部１７を備えた質量体１１と、免震対象物１に設けられると共に、質量体１１を揺動可能に下方から支持する質量体支持体１２と、質量体１１の揺動時に導体部１７が磁束を通過するように、磁石支持体１４により免震対象物に設けられた磁石１３と、を有して構成されたものである。【選択図】 図２
