Forced electroelastic vibrations of the piezoceramic resonators of simple geometric form

Abstract

Resonators’ forced electroelastic vibrations of rod, plate, and disk forms are examined. The piezoelectric
resonator’s admittance is established to be a product of its reactive conductivity of inter-electrode capacity
and the ratio of anti-resonance to resonance determinants. Experimental data are obtained and analyzed for
the 33.4*5.8*1.25mm rod and for 66.4*3.1mm disk made of TsTBS-3 ceramics. It is shown that admittance,
impedance, and phase shifts do not depend upon the regime of electric loading. At constant voltage, an
instantaneous power increases sharply at resonances and decreases at anti-resonances.
