Physico-mathematical modeling and informational technologies| Zusammenfassung: | Resonators’ forced electroelastic vibrations of rod, plate, and disk forms are examined. The piezoelectricresonator’s admittance is established to be a product of its reactive conductivity of inter-electrode capacityand the ratio of anti-resonance to resonance determinants. Experimental data are obtained and analyzed forthe 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, aninstantaneous power increases sharply at resonances and decreases at anti-resonances. |
