Zusammenfassung:To implement a desired vibration control effect in a simple configuration.SOLUTION: The vibration control device 1 comprises a weight 8, a lower bearing device 3 coupled to a building 100, an upper bearing device 6 coupled to the lower bearing device 3 and the weight 8 and damping devices 7X, 7Y connected parallel relative to the upper bearing device 6 for controlling an adjustment spring constant (kX'),(kY') of the upper bearing device 6. The damping device 7X is adjusted to an optimal resonance vibration frequency (ωOPT*X) synchronized to a natural frequency of the building 100 in X direction by controlling the adjustment spring constant (kX') of the upper bearing device 6 in X direction. The damping device 7Y is adjusted to an optimal resonance vibration frequency (ωOPT*Y) synchronized to a natural frequency of the building 100 in Y direction by controlling the adjustment spring constant (kY') of the upper bearing device 6 in Y direction.SELECTED DRAWING: Figure 2 【課題】簡易な構成によって、所望の制震効果を発揮する。【解決手段】制震装置1は、錘8と、建物100に連結された下支承装置3と、下支承装置3及び錘8に連結された上支承装置6と、上支承装置6に対して並列に接続され、上支承装置6の調整バネ定数(kX´)、(kY´)を制御する減衰装置7X、7Yと、を備える。減衰装置7Xは、上支承装置6のX方向における調整バネ定数(kX´)を制御することにより、建物100のX方向における固有振動数に同調させた最適共振振動数(ωOPT・X)に調整する。減衰装置7Yは、上支承装置6のY方向における調整バネ定数(kY´)を制御することにより、建物100のY方向における固有振動数に同調させた最適共振振動数(ωOPT・Y)に調整する。【選択図】図2
