部が連通的に接続され上記鉛直タンク部の上部に
それぞれ気密空気室が形成された液体タンク型Ｕ
字状制振タンクにおいて、上記両鉛直タンク部の
内側端壁を外側端壁に対し、それぞれ気密に相対
的に平行移動して上記両鉛直タンク部の水平断面
積を拡縮可能とすることを特徴とするＵ字状制振
タンクの固有振動数調節装置。 A liquid tank type U in which vertical tank parts are connected in communication with the front and rear ends of the horizontal tank part, and airtight air chambers are formed in the upper part of each of the vertical tank parts.
The character-shaped vibration damping tank is characterized in that the inner end walls of both vertical tank parts are moved parallel to each other in an airtight manner relative to the outer end wall, so that the horizontal cross-sectional area of both vertical tank parts can be expanded or contracted. A natural frequency adjustment device for a U-shaped damping tank.
