Modeling and experimental verification of the thin multi-electrode piezoceramic bars' forced vibrations
This paper is devoted to analysis of the multi-electrode piezoceramic bars' forced vibrations. Analytical model is built for a thin and narrow piezoelectric ceramic bar with three pairs of divided electrodes on the upper and lower main surfaces. The formulae for input admittance, characteristic (resonant and anti-resonant) frequencies as well as for transform ratio are obtained. The fundamental modes of vibrations of thin piezoelectric bar and their odd and even overtones are studied.
