Abstract

In this paper, admittance is introduced to represent electro-mechanical characteristics of piezoelectric structures and to predict the performance of piezoelectric shunt system. It is shown that admittance of the piezoelectric structure is proportional to the dissipated energy in the shunt circuit. Admittance is used as a design index to construct the piezoelectric shunt system and obtained by finite element method. Vibration reduction of the piezoelectric structure with shunt circuit is realized by experiments. Damped system response of piezoelectric structure in frequency and time domain proved that admittance is proportional to the performance of piezoelectric shunt system. Therefore, a new design method of piezoelectric shunt system using admittance analysis is proposed to save design cost of the piezoelectric structure.
