Drozdenko O. Design of electroacoustic transducers, taking into account cavitation, electrical and thermal loads

The thesis is devoted to solving the actual problem of piezoceramic electroacoustic transducer structures development, taking into account operational loads, which will ensure the long efficient operation of these transducers in the liquid. In work the physical reasons of cavitational, electric and thermal loadings emergence in radiating transducer designs depending on operating conditions are investigated, their consequences are considered, approaches are developed and analytical ratios for values assessment of the specified loadings are received. The techniques of durability parameters numerical estimation for a transducer designs in the concrete conditions of their loadings are developed.
