ABSTRACT:
A system for stabilizing sensitive apparatus from translational and rotational vibrations of the structure on which the apparatus is mounted uses a conventional bearing or a flexure pivot to achieve angular isolation in series with a compliant isolator for attenuating translational vibrations. Wideband corrective torques are applied to the apparatus by linear actuators connected between the vibrating structure and the sensitive apparatus, in parallel with the isolator and bearing combination. Motion of the apparatus is sensed by rate gyros and angular accelerometers mounted on the sensitive apparatus. These instruments through servomechanism loops, drive the linear actuators to oppose the motions.
