Designing of ultrasonic oscillation systems for technological devices

During the design stage, the modeling of a technological ultrasonic oscillator (UOS), combined with a step-exponential waveguide-concentrator was carry out. An analysis of the obtained modeling results and comparison tests of the constructed oscillation system, which was designed subject to the modeling results, verify the adequacy of the selected technique. The modeling calculations have adequate accuracy and allow the formulation of recommendations for ultrasonic oscillation systems development.
