Vibration Control of Laminated Composite Beams using Active Constrained Layer Damping Treatment

능동구속감쇠 기법을 이용한 복합적층보의 진동제어

The flexural vibration of laminated composite beams with active and passive constrained-layer damping has been investigated to design structure with maximum possible damping capacity. The equations of motion are derived for flexural vibrations of symmetrical, multi-layer laminated beams. The damping ratio and modal damping of the first bending mode are calculated by means of iterative complex eigensolution method. This paper addresses a design strategy of laminated composite under flexural vibrations with active control.
