Abstract

This article describes the design of an ultrasonic piezoelectric transducer with increased power. The increase in power is achieved by summing the power of several Langevin converters installed on a single radiating patch. The conducted studies have shown that the main disadvantage of this piezoelectric transducer is the destruction of piezoceramic rings due to the high uneven distribution of oscillation amplitudes in the region of their attachment. Theoretical and experimental studies have made it possible to optimize and eliminate the main drawback of the piezoelectric transducer. In this case, the maximum uniformity of the distribution of vibration amplitudes in the area of attachment of piezoceramic rings was chosen as an optimization criterion.As a result of the research, an optimized design of high-frequency converters has been developed.It has been determined that the installation of 9-11 radially arranged piezoceramic packages provides the minimum non-uniformity of oscillations in the area of piezoring attachment, while the transducer designed for 30 kHz provides acoustic power of at least 1450 W with an efficiency of 78%.
