Abstract
Exact dynamic analysis of 2-2 cement–based piezoelectric transducers is presented based on the theory of piezo-elasticity in this article. The solutions of four different kinds of 2-2 cement–based piezoelectric transducers under external harmonic load are obtained by using the displacement method. The effects of polarization direction of piezoelectric layers and thickness and distance of piezoelectric layers on the responses of the transducers are discussed. Comparisons with other related experimental investigations are also given, and good agreement is found. The results obtained in the present investigation provide a comprehensive understanding and can be referenced in the design of 2-2 cement–based piezoelectric transducers.
