Filipova N. Receiving and sound of radiation of a cylindrical eleсtroelastics transducer matching layer

The thesis is devoted to the development and experimental verification of theoretical bases of calculation electroelastic cylindrical transducers with a matching ring layer. In dissertation work the theoretical methods of calculation are created and determined the effect of matching the transition layer on the physical processes of formation of the main fields of energy conversion. Three tasks hydro electroelasticity is posed and solved for receive mode and single–mode radiation of sound and admission multimode converter with the matching layer. As a result of implementation of numerical researcher influence of thickness of the material layer and the electrode geometry, changes in electrical resistance strain on basic physical and foster fields radiating transducers. The theoretical results experimentally verified according to the measurement of spatial and amplitude-frequency characteristics.
