The construction development of the resonance concentrating link with enlarged radiating surface

In this paper the results of studies of functional possibilities of the optimization of geometric sizes and the construction development of specialized resonance concentrating link with enlarged radiating surface are presented. Developed theoretical model lets determine the value of longitudinal and transverse sizes of each part of concentrating link providing the achievement of required features of the ultrasonic vibrating systems (gain factor of the unit and its resonance frequency). To verify the efficiency of designed model the determining of geometric sizes of resonance concentrating link was made by the finite-element complex, which showed, that the disagreement did not exceed 10%. The efficiency of proposed model at the determining of size and resonance characteristics of concentrating link was proved by the experiments. Theoretical and experimental studies help to optimize the size of concentrating link, vibrating system developed on its base provides the enlargment of radiating surface in more than 6 times without decrease of radiation intensity for the realization of technologies of cavitation treatment of liquid media.
