Abstract

The nature of the polarization of piezoceramic elements plays an important role in the construction of piezoceramic hydroacoustic transducers with dynamically controlled parameters from the electrical side. However, to quantify this role, depending on the polarization, radial or circumferential, of the transducer's piezoelectric elements, appropriate calculation ratios are required. By the method of coupled fields in multiconnected domains taking into account the connectivity of electric, mechanical and acoustic fields during energy conversion and acoustic interaction of transducer elements during its formation, expressions for the named physical fields depending on amplitudes and phases are calculated.
