Abstract

The active damping concept of a wind-tunnel model was researched and a parallel type active damper was designed based on the piezoelectric effect of a stacked piezoelectric ceramic actuator. According to sting support system and its aerodynamic characters

the sting damping principle was analyzed and the active anti-vibration structure with piezoelectric ceramic stack actuators was proposed based on the anti-vibration principle. Then

a real-time control system was equipped for the anti-vibration structure. Aiming at the characteristics of displacement hysteresis

a control program based on a PD regulator was proposed. Finally

a ground experiment platform was built and the hammering method and vibration method were utilized to do experiment for the active damper.The experimental results show that the active sting damper improves the damping ratio of the sting and shows higher damping vibration abilities on both pitch and yaw directions

especially on the pitch direction. When the damper is involved the system

the damping ratio of the system increases from 0.009 to 0.092 and the remained vibration amplitude is about 25%. The experimental results demonstrate the effectiveness and feasibility of the sleeve-type active damper.
