Abstract
The objective of the invention is to provide an active vibration restraining actuating mechanism applied to wind tunnel model vibration decoupling control. The active vibration restraining actuating mechanism comprises an actuating mechanism base, an actuating mechanism baffle disc and a balance strut. The actuating mechanism base and the actuating mechanism baffle disc are connected together through studs. Piezoelectric stack actuators are installed between the actuating mechanism base and the actuating mechanism baffle disc. The tail conical surface of the balance strut is matched with the conical hole of the base of the actuating mechanism baffle disc and fixed on the base of the actuating mechanism baffle disc through a pressing cover. Axial vibration of the piezoelectric stack actuators is amplified and converted into pitching vibration and yawing vibration of the free end of the balance strut or the coupled vibration of the both, and an active control strategy is adopted so that the vibration response of the model end caused by wind loading exciting can be effectively reduced.
