ACTIVE SEMIACTIVE CHANGEOVER TYPE SEISMIC ISOLATION DEVICE
To perform a more-detailed control power during vibration applying time to generate control power for restricting oscillation of the structure at an active type seismic isolation device for outputting a control power to be applied from a driving device to a structure under application of pressure liquid got from a pressure storing device that stores pressure liquid.SOLUTION: This invention relates to a seismic isolation device 1 comprising a conversion device 5 for changing a vibration energy inputted to a structure into fluid energy, a pressure storing device 3 for accumulating converted fluid energy as pressure liquid, a driving device 2 for outputting a control power to be applied to a structure under application of the stored pressure liquid, a servo valve 25 connected between each of the cylinder chambers 23, 24 of the driving device 2 and the pressure storing device 3. A flow rate control valve 26 is connected between both cylinder chambers 23, 24. The driving device 2 closes the flow rate control valve 26 while allowing the pressure liquid got from the pressure storing device 3 to pass through the servo valve 25 and then controls an opening degree of the flow rate control valve 26 while shutting off a passage of the pressure liquid got from the pressure storing device 3 through the servo valve 25 under a specified condition when the driving device 2 should be active controlled.SELECTED DRAWING: Figure 8
【課題】圧液を蓄えた蓄圧装置からの圧液を用いて駆動装置から構造物に付与すべき制御力を出力するアクティブ型制震装置において構造物の揺れを抑制するために制御力を発生する加振の時間帯中でより詳細に制御力を制御する。【解決手段】構造物に入力した振動エネルギを流体エネルギに変換する変換装置５と、変換された流体エネルギを圧液として蓄積する蓄圧装置３と、蓄積された圧液を用いて構造物に付与すべき制御力を出力する駆動装置２を備え、駆動装置２の各シリンダ室２３、２４と蓄圧装置３との間にサーボ弁２５が、両シリンダ室２３、２４間に流量制御弁２６が接続された制震装置１において駆動装置２は加振の時間帯の内、駆動装置２をアクティブ制御すべきときに蓄圧装置３からの圧液のサーボ弁２５の通過を許容しながら流量制御弁２６を閉じ、一定条件ときに蓄圧装置３からの圧液のサーボ弁２５の通過を遮断しながら流量制御弁２６の開度を制御する。【選択図】図８
