When implementing the project, a comprehensive research structure was applied, in which the choice of a specific type of research was determined by the goals and objectives that were solved at individual stages of its implementation. First, when developing mathematical models of the processes of shaping by cutting, an approach based on numerical and simulation modeling was used, and experimental design methods and regression analysis were used to determine some empirical parameters of the models.
For the intensive development of scientific and technological progress, it is necessary to use new materials with unique desired properties, such as high sorption ability, superconducting properties, high ability to accumulate electric charge, etc. Despite the intensive development of electrical engineering and an increase in the number of portable electronics, it is necessary to use portable sources energy with high rates of charge capacity and cyclability. Currently, one of the most promising is lithium current sources (LCS). Therefore, we can say with confidence that the search for new electrode materials that would provide the above features is undoubtedly an urgent task.
A new concept of constructing an automatic hardness gauge and a surface roughness meter has been created, unlike existing methods, it adheres to its TONTOR measurement technique. New approaches to obtaining microhardness and surface roughness of precision workpieces are based on the physical and mathematical principles of TONTOR technology, which involves measuring the parameters of interacting objects with respect to their field structures.
A new competitive technology has been developed for the molding of structural products from traditional and nanomodified polymer composite materials (PCM) based on the use of effective low-frequency ultrasonic (US) cavitation modes in liquid polymer media. Effective processing parameters were established for the basic technological operations of preparing nanosuspensions, preliminary ultrasonic treatment, disintegration and mixing in the preparation of liquid nanomodified polymer compositions
The basic part of the problem of combining physically heterogeneous components in the creation of executive modules of automated systems with programmable control is solved.
The results of the study of the features of the emergence and maintenance of the phenomenon of ultrasonic cavitation and the revealed patterns are the basis of the original design solutions of technological cavitation equipment, which allowed to increase the efficiency of many technological processes and the reliability and operational longevity of cavitation technological equipment
For the first time in Ukraine a prototype of the "point-to-point" wireless communication system in terahertz frequency band of 130-132 GHz was developed with usage of impulse ultra wideband signals for local computer networks and sensors data transmission networks which based on the proposed “non-energy” reception method of impulse ultra wideband signals.
The work is aimed at creation of high-efficiency heat regenerators of gas turbine units (GTU) of the gas transportation system of Ukraine. It is proposed to use highly effective heat exchange surfaces from the tubes of the spiral corrugated profile with high heat and aerodynamic characteristics for heat regenerators GTU, which will ensure a reduction of mass-dimensions by 30- 40% in comparison with heat exchangers made of smooth round tubes and an increase in the KPD GTU from 18-25% to 38-41%.
