A Finite-Element Approach to the Analysis of Tangentially Polarized Piezoelectric-Ceramic Free-Flooded Cylinder Transducers

Abstract

An approximation method is presented for solving the equations of motion that describe the vibration of a tangentially polarized piezoelectric- ceramic, staved, free-flooded cylinder transducer immersed in an infinite acoustic fluid medium. The mathematical model that is developed uses the finite- element method to calculate the vibrational characteristics of the elastic cylinder and the acoustic pressure field of that portion of the fluid which closely surrounds the cylinder out to a spherical surface. Analytical methods are used to obtain the boundary conditions for the spherical surface. This technique can be used to predict the transducer's complex electrical impedance, transmitting voltage response, and radiated power as functions of frequency.
