On the Impact of the Physical Properties of Piezoceramic Materials on the Mechanical Fields of Cylindrical Radiators of Screened Systems

By means of the numerical experiment, the impact of the physical properties of piezoceramic materials on the characteristics of the mechanical fields of cylindrical radiators has been studied in their functioning as part of screened systems. It has been shown that the taking into account of the coupling of electric, mechanical and acoustic fields in energy conversion processes and the coupling of the acoustic fields of the radiator in terms of their functioning within systems changes the current understanding of the impact of the physical properties of the compositions of piezoceramic elements on the effectiveness of acoustic radiation by such systems. Specific characteristics of the mechanical fields of radiators, which, in terms of quantity, are mostly dependent upon the physical properties of piezoceramic materials, and the degree of their change in the case of the replacement of materials have been established.
