ACTIVE CONTROL OF POWER FLOW FROM A VIBRATING RIGID BODY TO A FLEXIBLE PANEL THROUGH 2 ACTIVE ISOLATORS

Active control of harmonic vibratory power flow from a rigid body thro ugh two active isolators to a simply supported flexible panel is inves tigated theoretically and experimentally. Power flow as a result of mo ments acting on the rigid body as well as horizontal and vertical forc es is taken into account. Both theoretical and experimental results sh ow that over a wide frequency range, an active isolation system consis ting of a force actuator in parallel with a passive elastic element ca n demonstrate substantial performance improvements over the simple pas sive elastic system acting alone.
