Vibromechanical Characteristics of the Emitting Shells of Small-Sized Low-Frequency Hydroacoustic Piezoelectric High Power Density Transducers

Abstract

Making the sound radiator body, working as radiating shell, is one of the most laborious and complicated technological operations in the technological process of manufacturing hydroacoustic transducers. Making the shell of the longitudinal-bending sonar with piezoelectric active element by laser 3D-printing from metal powders eliminates the problem of encapsulation, resistance to hydrostatic pressure and reduces radiator's parameters dispersion to facilitate its configuration.
