Kinetic Analysis of the Mechanism of Self-Induced Vibrations of the Mass Concentration of Dispersed-and-Solidphase Particles into a Hydro-Ultrajet

The paper considers the problem of improving the quality and productivity of materials processing using hydroabrasive cutting technologies. When performing the kinetic analysis of the mechanism of self-induced vibrations of the mass concentration of dispersed-and-solidphase particles to a hydro-ultrajet, the sequencing of the mixing process is examined. The analysis takes into account the automatic feed of the particles to the hydro-ultrajet due to their ejection into the initial section of the focusing abrasive-liquid nozzle. The mechanism of generation of self-induced vibrations in the feed of the dispersed-and-solidphase particles to the hydro-ultrajet is described. It illustrates the factor of intraoperative physico-technological heredity in hydroabrasive processing and hydroabrasive cutting of materials and products. The design and technological solutions developed on the basis of theoretical provisions, after a corresponding expert-analytical evaluation with minimal technical and economic costs for their implementation, will significantly improve the physical and technological parameters of quality and efficiency of hydroabrasive processing and hydroabrasive cutting of materials in the production of critical parts.
