Abstract:
The radial vibration piezoelectric transducers have been widely used in the field of underwater for their large radiation area and uniform directivity in the radial direction as well as high receiving sensitivity and stable performance. With the development of the high power ultrasonics, a class of high power radial vibration piezoelectric transducers are presented and developed which are widely used in the application of sonochemistry and sewage treatment and other fields in recent decades, the development and application of the radial vibration piezoelectric ultrasonic transducer is outlined. The new developments and the techniques of some new kind of high-power radial vibration composite ultrasonic piezoelectric transducer including:piezoelectric tubular transducer,composite tubular transducer,radial composite piezoelectric ultrasonic transducer are mainly introduced, and the corresponding technology problems for the design of the transducers are analyzed and prospected.
