The Finite Analysis of the Piezoelectric Shell Stack Transducer

Abstract:

Novel piezoelectric shell stack in radial direction had been developed. The shell stack was composed of inner and outer shells which are bonded with each other by epoxy resin. The vibration and electromechanical characteristics of the piezoelectric shell stack were modeled and simulated by Finite Element Analysis (FEA). The send voltage response (SV) of both single and double shells under water were computed. Particularly the analytical results of shell stack presented in resonance frequency varying with the radius and thickness had been compared with experiments. The computations show agreement with the experimental results, and the errors are less than 1.28%.
