VIBRATION SUPPRESSING DEVICE FOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration suppressing device for a structure capable of rapidly and suitably suppressing vibration in a prescribed vibration mode of the structure.SOLUTION: Supporting body displacement parameters dy/dt and y showing displacement of a supporting body are detected, and contribution degree parameters βU(1)-βU(3) showing a contribution degree of a prescribed vibration mode of a structure with respect to the vibration of the structure are acquired. Further, a control parameter Z0 for controlling vibration control force of an active damper is calculated so that external force acting on the structure in accordance with the vibration in the prescribed vibration mode of the structure is canceled by the vibration control force of the active damper in correspondence with the detected supporting body displacement parameters dy/dt and y and the acquired contribution degree parameters βU(1)-βU(3).SELECTED DRAWING: Figure 5
【課題】構造物の所定の振動モードの振動を迅速かつ適切に抑制することができる構造物の振動抑制装置を提供する。【解決手段】支持体の変位を表す支持体変位パラメータｄｙ／ｄｔ、ｙが検出されるとともに、構造物の振動に対する構造物の所定の振動モードの寄与度合いを表す寄与度合いパラメータβＵ（１）〜βＵ（３）が取得される。また、検出された支持体変位パラメータｄｙ／ｄｔ、ｙ、及び、取得された寄与度合いパラメータβＵ（１）〜βＵ（３）に応じて、構造物の所定の振動モードの振動に伴って構造物に作用する外力がアクティブダンパの制振力によって打ち消されるように、アクティブダンパの制振力を制御するための制御パラメータＺ０が算出される。【選択図】図５
