High-Frequency Ultrasonic Radiator Power Increase by Means of Summation of Vibrations of Symmetrically Arranged Langevin Transducers

The article focuses on the research of processes summation ultrasonic vibrations individual Langevin transducers symmetrically arranged a common summator. This design could be used to solve problem increasing power high-frequency radiator by means transducers. results presented theoretical and experimental investigations supported possibility symmetrical diametrical when they are transformed into longitudinal vibrations. As result, new scheme for construction was developed that provides symmetry uniformity vibration amplitude distribution piezoceramic elements. made it possible eliminate damage establishes an acoustic (continuous mode) 1450 W at efficiency 78% is achieved from 9 11 resonant frequency 30.05 kHz with 26 µm summed. use this increased will provide intensification in various areas industry.
