Abstract

Like every dynamic output device, piezoceramic (PZT) actuators have their own output characteristics. The output characteristics of PZT actuators are functions of frequency and may be treated as frequency independent only in a certain frequency range. The dynamic excitation provided by a PZT actuator depends on its dynamic characteristics and structural mechanical impedance. The conventional method of using the statically determined induced moment or the force of PZT actuators as forcing functions is not correct. This paper uses a simple example, a PZT actuator-driven one-degree-of-freedom spring-damper-mass system, to illustrate the methodology used to determine the dynamic characteristics of PZT actuators and the structural response based on the concept of structural impedance.
