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 through two active isolators to a simply supported flexible panel is investigated theoretically and experimentally. Power flow as a result of moments acting on the rigid body as well as horizontal and vertical forces is taken into account. Both theoretical and experimental results show that over a wide frequency range, an active isolation system consisting of a force actuator in parallel with a passive elastic element can demonstrate substantial performance improvements over the simple passive elastic system acting alone.
