VISCOSITY MASS DAMPER WITH SPRING
PROBLEM TO BE SOLVED: To provide a viscosity mass damper including a spring capable of adjusting either a dynamic characteristic or a vibration characteristic by a simple structure.SOLUTION: This invention comprises a viscosity mass damper in place of a conventional viscosity mass damper with a spring including a direct-acting shaft provided with a male thread along a displacement direction of a direct-acting displacement, a rotor provided with a female thread fitted with the male thread, a frame for rotatably supporting the rotor and viscosity fluid filled in a clearance between the frame and the rotor, and an elastic member for generating an elastic reaction force in response to the direct-acting displacement. The viscosity damper and the elastic member are connected in series and the elastic member includes either a single elastic plate or several elastic plates that are sheared or deformed in correspondence with the direct-moving displacement and an actuator for generating either a compression strain or a tension strain that is faced to a direction crossing with the displacement direction of the direct-moving displacement at either the single elastic plate or several elastic plates.SELECTED DRAWING: Figure 1
【課題】 簡易な構造により動特性または振動特性を調整できるバネ付き粘性マスダンパーを提供しようとする。【解決手段】従来のバネ付き粘性マスダンパーにかわって、直動変位の変位方向に沿って雄ねじを設けられた直動軸と前記雄ねじに嵌めあう雌ねじを設けられた回転体と前記回転体を回転自在に支持するフレームと前記フレームと前記回転体との隙間に封入された粘性流体とを有する粘性マスダンパーと、前記直動変位に対応して弾性反力を発生する弾性部材と、を備え、前記粘性ダンパーと前記弾性部材とを直列接続され、前記弾性部材が前記直動変位に対応して剪断変形する単数または複数の弾性板と単数または複数の該弾性板に前記直動変位の変位方向に交差する方向に向いた圧縮歪または引張歪を発生させるアクチエータとを有する、ものとした。【選択図】 図１
