The influence of the material of the ultrasonic vibration concentrator on the amount of the amplitude of mechanical vibrations
Abstract
Background. The purpose of this article is to study the effect of ultrasonic vibrations on the surface of a liquid for subsequent use in electric arc surfacing processes. Materials and methods. To reach this goal, a duralumin ampoule-step concentrator was used at a frequency of 21400 Hz. Measurements were carried out on a piezoelectric converter with a frequency of 19-24 kHz, as a liquid – industrial water. Results. The dependences of the height of the radiating surface of the ultrasonic vibration concentrator (USVC) on the surface of the liquid on which the impact and formation of the “hole” occur are determined; the parameters of the ultrasonic wave passing through the separation of two media water-air are determined; the dimensions of the depth of the “hole”, pressure and surface area at maximum exposure are determined. Conclusions. The results obtained can and will be used in the processes of electric arc surfacing of metals as a shaping factor.
