Paper Abstract

This paper presents the theoretical development and the experimental verification of a dynamic model of distributed piezoelectric (PZT) actuators locally coupled with 2D structures. The model includes the dynamic interaction between PZT actuators and their host structures. An analytical solution of the moment (or force) outputs of the PZT patch actuators has been developed based upon the input impedance of the piezoelectric actuator and the mechanical impedance of host structures. A simply-supported thin plate with surface-bonded PZT patches was built and tested so that the ability of the impedance approach to predict the dynamic performance of the actuator and intelligent structures has been verified. When compared with conventional static models or quasi-static models, the impedance modeling method offers insight into the dynamics and electromechanical coupling of the integrated PZT/substrate systems and more accurately predicts the actuation of induced-strain actuators.
