Scientific results from studies on the resonant electromechanical vibrations of piezoceramic thin-walled shells of revolution,
their fragments, and segmented cylinders are analyzed, systematized, and generalized. Considerable attention is focused on
experimental studies of resonant vibrations. It is shown that the modes in which deformation occurs inphase throughout the
volume are of the highest intensity in all piezoceramic shell structures

The scientific results on the resonant electromechanical vibrations of piezoceramic plates in the form of disks, rings, and
polygons obtained over the last 30 years are analyzed, systematized, and generalized. Emphasis is on experimental methods.
It is shown that all piezoceramic plates have vibration modes at which deformations are in-phase over the entire volume of
the body

The resonant radial vibrations of a thin piezoceramic disk with solid electrodes and thickness polarization are considered as an example to study the influence of the geometry of piezotransformer transducers on their electric potentials and the mutual influence of neighboring transducers__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 2, pp. 75–80, February 2005. 相似文献

The influence of dielectric, mechanical, and piezoelectric energy losses on the electroelastic characteristics of a piezoelectric transformer plate is analyzed. It is shown that only mechanical loss occurs at resonance frequencies 相似文献
