Air flow in wind tunnel usually results in large vibration of model support system, which can influence the accuracy and reliability of wind tunnel test. Therefore, it is crucial to study and accomplish the vibration control technique of model support system. Based on electromechanical coupling characteristics of piezoelectric material and active vibration control principle the piezoelectric package embedded model support system was designed. Meanwhile, according to rigid-flexible coupling dynamics theory the structure vibration simulation model of model support system was built. Furthermore, associated with classic PID control arithmetics the integrated structural and control simulation model of model support system was built for simulating active vibration control. Finally, considered nonlinear contact factor the finite element model of piezoelectric package embedded model support system was built for inspecting contact strength and optimizing embedding style. These simulation results show that the piezoelectric package embedded model support system has fine vibration control capability and structural safety, which can be applied to actual engineering efficiently.
