摘 要：Synthetic jet technology is one of the hotest topic of active control technology in the hydromechanics field in recent *** jet actuator is the key device,and its active element is a piezoeletric *** this paper,the forced vibration of the circular piezoelectric composite plate is investigated by means of the energy method.A simplified dynamic equation which is similar to the single degree of freedom（SDOF）system is *** equivalent damping parameter is introduced to correct the dynamic *** with the expermental data,the theoretical results show a good accuracy when the driving frequency is lower than the resonant *** performance of the circular piezoelectric composite plate vibrator is discussed.
