FIELD: ultrasonic engineering; ultrasonic vibration systems for engineering purposes. ^ SUBSTANCE: proposed ultrasonic device that can be used for cleaning (ultrasonic baths), dispersing, homogenizing, and emulsifying materials has ultrasonic converter accommodating waveguide radiating system which is in acoustic contact with converter. Waveguide radiating system has coaxially installed bending-vibration waveguides separated by longitudinal-vibration waveguide sections. Bending-vibration waveguides are disposed in planes perpendicular to axis of longitudinal-vibration waveguide axis and spaced lambda/4 apart, where lambda is longitudinal-vibration wavelength. Thickness of each bending-vibration waveguide installed at antinode point of longitudinal vibrations is lambda/15. Thickness of each of remaining bending-vibration waveguides is lambda/18. Thicknesses of converters are set by way of calculations and experiments including attaining of maximal possible cavitation capacity during liquid sonication. Total length of radiator is a multiple of lambda/2. ^ EFFECT: enhanced radiation effectiveness. ^ 6 cl, 2 dwg
