ACTIVE TYPE VIBRATION CONTROL DEVICE
PROBLEM TO BE SOLVED: To provide an active type vibration control device capable of exhibiting high vibration control effect at an initial stage of vibration occurrence.SOLUTION: A storage device (40) stores a control signal (x(t)) in advance which is calculated based on a reference vibration (h(t)) detected at prescribed vibration control object positions (Pd, Pd1-Pd4) of a face material (10) when a prescribed reference signal is input to an excitation actuator (30) in advance and a vibration control object vibration (a(t)) detected at the vibration control object positions (Pd, Pd1-Pd4) when prescribed out-of-plane vibration is input to the face material (10) in advance. A control device (50) outputs the control signal (x(t)) to the excitation actuator (30) when sensors (20, 21-24) detect input of the specific out-of-plane vibration.SELECTED DRAWING: Figure 1
【課題】振動発生初期において高い制振効果を発揮できる能動型制振装置を提供する。【解決手段】記憶装置（４０）は、予め加振アクチュエータ（３０）に所定の基準信号を入力した際に面材（１０）の所定の制振対象位置（Ｐｄ，Ｐｄ１−Ｐｄ４）で検出される基準振動（ｈ（ｔ））と、予め面材（１０）に特定の面外振動が入力される際に制振対象位置（Ｐｄ，Ｐｄ１−Ｐｄ４）で検出される制振対象振動（ａ（ｔ））とに基づいて算出される制御信号（ｘ（ｔ））を予め記憶する。制御装置（５０）は、センサ（２０，２１−２４）が特定の面外振動の入力を検出した時に、制御信号（ｘ（ｔ））を加振アクチュエータ（３０）に出力する。【選択図】図１
