Analysis of Piezoelectric Disks and Cylinders Using Finite Element Method.

Abstract

Resonance characteristics of piezoelectric transducer elements were analyzed using the finite element method (FEM). We developed a computer program based on the axisymmetrical element formulation. Using this program, we determined resonance frequencies and vibration modes of cylindrical and disk-shaped elements of BaTiO3, PZT-4 and PZT-5A ceramics. The resonance frequencies were obtained by the FEM analyses for the stress-free boundary condition. Resonance vibration modes were also determined and found to be quite complex.
