ABSTRACT:
A method of attenuating vibrations, and a vibration attenuating actuator for attachment to a vibration transmitting structural member include an annular proof mass for attenuating vibrations. The proof mass is concentrically mounted without bearings on the strut so as to attenuate vibrations being transmitted therethrough without imparting a moment to the strut, and without affecting the structural integrity of the strut. The annular proof mass is moved parallel to the strut's longitudinal axis so that the actuator imparts a vibration attenuating force coaxial with the strut's longitudinal axis. The actuator may be used with feedforward and feedback controllers.
