The article proposes technical solutions for increasing the efficiency of finishing-cleaning and hardening processing parts on basis rotor-screw technological systems. essence, design features capabilities system with a rotating container are disclosed, which allows one to expand range resulting displacement vectors, granules abrasive medium processed parts. Ways intensification their by means vibration activation process providing combined effect mass loading large small amplitude...
The article discusses energy aspects of details' hardening with convective flows freely moving indenters under the conditions rotating electromagnetic field. Results theoretical studies kinetics movement ferromagnetic are presented and model state magnetic liquefied layer is proposed, formed influence
The article presents the morphological research results of galvanized coating applied to metal surface in course mechanical and chemical synthesis realized under vibrowave process system conditions. paper reveals specifics morphology, its activating role free-moving indentors formed impact low-frequency vibrations positive influence on operational performance part layer. advantages this application method are presented comparison with conventional methods.
Features of parts machining in rotor-screw technological systems are presented. It is shown that the mass load, consisting processed and granulated working medium, located along internal perimeter screw rotor asymmetrically to axis its rotation. In this regard, there difficulties designing machines drive, rationale for optimal power. A technique proposed calculating drive power machines, which makes it possible carry out a techno-economic assessment study their applicability...
The ways of productivity increase in details finishing-strengthening processing executed rotor-screw technological systems are presented. It is shown that the use machines makes it possible to combine parts machining using a vibrating field with large amplitude oscillations and their transportation streamlined form production organization. Two main directions rotor-helical stimulation identified: on basis structural changes screw rotor, as working element machine by equipping rotor...
The paper reports the results of experimental research on substantiation criterion for steel strengthening effectiveness established a basis an energetic approach to consideration mechanism surface layer formation with dynamic methods plastic forming. Using analogy between processes energy absorption crystal lattice under mechanical loading and heating, work demonstrates that maximum specific which can absorb corresponds value equal difference heat content (enthalpy) material in solid state,...
Abstract The article discusses one of the main stages products’ preparation for disposal, providing their cleaning from contamination; it is shown that most promising methods treatment are mechanochemical based on use a different vibration spectrum processing substance. Depending nature contamination, material and shape processed parts, conditions (mode, working environment, washing dissolving liquids) can be varied. Based studies carried out, has been established surface depends directly...

The analysis of the results experimental studies production zinc coverings by way vibration chemical and mechanical synthesis words.
On the basis of thermodynamic concepts process, we proposed an energy model that reflects mechanochemical essence coating forming in terms vibration technology systems, which takes into account contribution to formation coating, increase unavailable due growth entropy, elastic-plastic crystal lattice distortion as a result mechanical influence working environment indenters, surface layer internal change occurs chemical interaction contacting media. We adhesion strength local volume modified...
The tendencies in the current market development of educational services based on integration processes state and mechanisms are considered. Particular attention is given to a approach for formation college strategy functioning increase competitiveness. It shown that peculiarities marketing activity should be connected with higher education interact not two parties (service producer consumer), but four types subjects: consumers – parents; em-ployers which interested frame refresh works...
The application of dimensional-accuracy analysis in the development new and improvement existing designs electromechanical sensors is shown, which makes it possible to establish reasons for high labor intensity fitting adjustment work during their manufacture identify ways reduce it. most rational solutions are presented ensure accuracy design an pressure sensor.
