VERTICAL VIBRATION CONTROL STRUCTURE FOR CANTILEVER BEAM FRAME

摘要

PROBLEM TO BE SOLVED: To provide an effective and suitable vibration control structure capable of suppressing vertical vibrations of a cantilever beam frame.;SOLUTION: A tuning type additional vibration system 10 is constituted by installing a damper support beam 11 which has its base end part supported and its tip part made free and can vibrate relatively to a cantilever 3 constituting a cantilever beam frame 1 at a side part of the cantilever 3 along the cantilever 3, and interposing a rotary inertia mass damper 12 between a tip part of the damper support beam 11 and the cantilever 3. The damper support beam 11 preferably has its vertical spring rigidity set so as to function itself as a tuning spring connected in series with the rotary inertial mass damper 12. The additional vibration system 10 may be provided with a special tuning spring 14 connected in series with the rotary inertia mass damper 12.;COPYRIGHT: (C)2014,JPO&INPIT
