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.

This paper is devoted to analysis of the electric loading conditions problem for piezoceramic resonators' forced vibrations. New simple experimental technique together with computing permits us to study many resonators' parameters: admittance, impedance, phase angles, power components, etc. for constant input voltage, constant sample voltage and constant sample current electric conditions based on experimental data for "as it is" regime.
