PROBLEM TO BE SOLVED: To provide a self-tuning TMD that eliminates a tuning step, saves time, and results in better overall performance for damping so as to reduce a dynamic response of a structure due to damping problematic modes.SOLUTION: A tunable mass damper incorporates a frame (14) and a voice coil (10) supported in the frame (14). A magnet (16) concentric with the voice coil (10) is movable relative to the frame via the voice coil (10). A plurality of flexures (18a and 18b), which have a first end extending from the magnet (16) and an arm (19) releasably coupled to the frame (14), are adjustable to an effective length for a desired frequency of reciprocation of the magnet (16).SELECTED DRAWING: Figure 1A

    【課題】同調ステップを取り除き、時間を節約し、減衰のためのより良好な全体性能をもたらして、減衰で問題のあるモードによる構造物の動的応答を低減する、自己調節型TMDを提供すること。【解決手段】同調マスダンパーは、フレーム(14)と、前記フレーム(14)内に支持されるボイスコイル(10)とを含む。前記ボイスコイル(10)と同心状の磁石(16)は、前記ボイスコイル(10)を介して前記フレームに対して移動可能である。前記磁石(16)から延長する第1端部と、前記フレーム(14)に開放可能に連結されるアーム(19)とを有する複数の撓み部(18a及び18b)は、前記磁石(16)の往復動の所望の周波数のための有効長に調整可能である。【選択図】図1A
