Abstract

The dynamic behavior of piezoelectric actuators bonded on structures are completely different from its static behavior. The strong interaction between actuators and host structures delivers the response of actuators and associated power supply to be closely dependent on the dynamic state as well as the configuration of the host structures. The paper presents a new electromechanical dynamic model of a pair of actuators featuring the combination of an in- plane longitudinal wave induced by the piezoelectricity and transverse vibration concordant with the bending vibration of the actuator-bonded beam. The analytical results display that both kinds of movement of piezoelectric actuator are coupled with each other and deeply involved into the bending vibration of the beam. Moreover, its in-plane displacement and velocity response to the exciting voltage imposed across the actuators are affected not only by the resonant frequency of a bending vibrating of the beam, but also by the resonant frequency of a longitudinal wave of the piezoelectric actuator and the virtual eigen frequency of longitudinal wave of the actuator which is imaged to have the same length as the beam. The final results show that the electrical admittance of the actuator is contributed by a static, dynamic capacity of the actuator and also has the dedication of both longitudinal wave and transverse vibration coupled with the bending vibrating of the beam.
