Claims (1)
、これら弾性体のバネ定数と質量体の質量により
決定される固有振動数で共振振動して上記基体の
振動を抑制するダイナミツクダンパにおいて、上
記弾性体内に液室を設けて内部に電気粘性液体を
封入するとともに、絞り流路を介して上記液室に
連通し、変形自在な弾性膜を室壁とする副液室を
設け、かつ上記絞り流路の内部に電界を形成する
電極を設けてこれを通電手段に接続して、該通電
手段により上記電極への印加電圧を変更するよう
になしたダイナミツクダンパ。 A dynamic damper in which a mass body is supported by an elastic body provided on a base body, and the vibration of the base body is suppressed by resonant vibration at a natural frequency determined by the spring constant of these elastic bodies and the mass of the mass body, A liquid chamber is provided in the elastic body and an electrorheological liquid is sealed therein, and a sub-liquid chamber is provided that communicates with the liquid chamber via a throttle channel and has a deformable elastic membrane as a chamber wall, and A dynamic damper comprising an electrode for forming an electric field provided inside a throttle channel and connected to an energizing means so that the voltage applied to the electrode is changed by the energizing means.
