VIBRATION SUPPRESSION DEVICE FOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration suppression device for a structure capable of attaining a desired vibration control power when a vibration of the structure is relatively low and a larger vibration control power can be attained when the vibration of the structure is relatively high, and reducing the production cost.SOLUTION: A cylinder is connected to a first location, a piston slidably moving within the cylinder is connected to a second location, and an inside part of the cylinder is defined into a first fluid chamber and a second fluid chamber each filled with viscous fluid. When the piston is present in the inner space, the first communication passage is communicated with the first fluid chamber and the second fluid chamber, a fluid amount of viscous fluid flowing between the first communication passage and the first and second fluid chambers is adjusted by a flow rate adjustment mechanism and the flow rate adjustment mechanism is controlled by the control means. A second communication passage communicated with the first and second fluid chambers is closed by a first pressure adjustment valve when the pressure of the viscous fluid in the first fluid chamber is less than a first predetermined value, released when it reaches the first predetermined value, it is closed by a second pressure adjustment valve when a pressure of the viscous fluid in the second fluid chamber is less than a second predetermined value and it is released when it reaches a second predetermined value.SELECTED DRAWING: Figure 1
【課題】構造物の振動が比較的小さいときに所望の制振力を得られ、比較的大きいときにより大きな制振力を得られるとともに、製造コストを削減できる構造物の振動抑制装置を提供する。【解決手段】シリンダが第１部位に連結され、シリンダ内を摺動自在のピストンが、第２部位に連結され、粘性流体が充填された第１及び第２流体室に、シリンダ内を区画する。ピストンが内側区間にあるときに、第１連通路が第１及び第２流体室に連通し、第１連通路と第１及び第２流体室との間を流れる粘性流体の流動量が流量調整機構で調整され、流量調整機構が制御手段で制御される。第１及び第２流体室に連通する第２連通路が、第１調圧弁により、第１流体室内の粘性流体の圧力が第１所定値未満のときに閉鎖され、第１所定値に達したときに開放され、第２調圧弁により、第２流体室内の粘性流体の圧力が第２所定値未満のときに閉鎖され、第２所定値に達したときに開放される。【選択図】図１
