Abstract

The paper deals with a theoretical study on the redial vibration of cylindrical piezoelectric transducers The differential equations of piezoelectric radial motion have been derived in terms of the radial displacement and electrical potential. Applying mechanical and electrical boundary conditions has yielded the characteristic equations of natural vibration. Numerical resutls of the fundamental natural frequency have been compared with experimental observations for the transducers of several sizes, and have shown a good agreement.
