ABSTRACT:
An active isolator with a closed-loop feedback control system which uses an actuator in parallel spring relation to a static load spring to control the dynamic vibration transmitted from a vibrating device over a broad band frequency range. A collocated sensor is installed to sense the vibration of the isolated element and is amplified and fed, filtered and amplified again, reversed in sign and fed directly into the actuator. No external synchronizing signal or processor is needed. This simple active control is practical only where the combined series dynamic stiffness of the structure and vibrating body is much less than or much greater than the active mount's dynamic stiffness.
