Gusak Z. Radiation sonar signals of cylindrical piezoceramic transducers with baffles

The thesis is devoted to the development of theoretical design bases cylindrical piezoceramic baffled transducers with power and compensated designs considering the interaction of electrical, mechanical and acoustic fields in them and practical realization of this bases. In dissertation the theoretical calculation methods were obtained and were determined the influence of construction elements of cylindrical piezoceramic transducers with baffles on physical fields, which are formed within transducers. The baffle is not closed annular layer. The "cross-cutting" problem of sound wave transmitting by baffled cylindrical transducer with consideration of influence on physical fields main design features of baffled transducers was set and solved. As a result of big count of researches the behaviors of the influences of features of transducer design were determined. On the basis of the systematic researches the practical recommendations on the implementation of established scientific principles in practical implementation cylindrical piezoceramic radiators were developed. The theoretical results were experimentally confirmed by measurements and comparison of beam patterns of transducer with baffle.
