New substances and materials

Applied a comprehensive approach to modeling various stages of the process of extrusion - forming and cooling products to the changing rheology and melt viscoelastic effects in it, that affect the final product configuration. The methodological approach allows the numerical simulation of the formation of products from polymeric materials, design extrusion-forming equipment based viscoelastic deformation effects of products and make adjustments to the design and process parameters to achieve the form of products, more relevant given.

A study and development of methodological support structural monitoring of the technical state of metallic structural elements of complex spatial objects are carried out, the technical implementation monitoring system based on the concept of Structural Health Monitoring in mock sample is made. The simulation and physical models of complex spatial diagnostic object – the tank for storage of hazardous substances are given, the adequacy of models is confirmed.

The technology of manufacturing of ceramic and metal superstrength composites (40 GPa compressive strength) superhard (30 GPa) reinforced materials based on boron carbide and boride of titanium or aluminum, nanostructured B6O by hot pressing. It is established that changing technological parameters of hot pressing allows controlling chemical, phase composition and structure (grain size, the geometric dimensions of the reinforcing component).

Theoretical studies of static and dynamic characteristics of the synthesized with the use of genetic-morphological approach high-speed spindle assembles for Electromechanical actuator clamping, tool clamping chuck.
Experimental studies of a prototype of a self-acting motor-spindle gear screw-nut, the results of which revised technical documentation. Developed recommendations of improvement of spindle assemblies and clamping mechanisms for multi-axis machines of new generation. Directions of further research have discribed.

The technical proposals for the manufacture of new information and measuring system based on the principles of two-parameter control and distance measurement and control positioning objects in the workspace of process equipment; methodology for new technology controls the distance the tool to the workpiece during processing on the basis of complex electromagnetic fields of different frequency ranges and combinations thereof, that is cross-checking the distance based on different physical principles of sensory modules; Principles of new technology controls the distance the tool to the workpi

New approach to computer-aided design of the gear manufacture are implemented. CAD is complex considered the design of gear hobs, analysis of the conditions of their operation, running abilitys, analysis and selection of appropriate option from the point of view of manufacturing technology and the geometry of gear cutting tools, the creation of three-dimensional models for control.

It is conducting preliminary studies and conducted experimental verification of the effectiveness of producing traditional and nano-modified carbon nanotubes reaktoplastichnih polymer composite materials by the determined application of low-frequency ultrasonic cavitation. A new procedure for the preparation of traditional and nano-modified reaktoplastichnyh polymer composites with the low-frequency ultrasonic cavitation.

Developed new technological foundations of obtaining the hollow articles by forming cold sheet stamping processes, including drawing, reducing and bulging. The novelty lies in the development of new methods of drawing, reducing and bulging, to create and use a special profiles deforming tool. Using this deforming tool provides a significant reduction of friction influence in the forming of articles, reduce deformation force and increase the degree of deformation in one stage.

Equations for the of the resonant frequency and Q-factor calculation for frequency-selective devices based on thin dielectric resonators are found. Calculation error is less than 1 ... 2% for frequency and 5 ... 7% for Q-factor These equations can be the base for automatisation of calculations during the design of the devices on the base of thin dielectric resonators.

Performed a comprehensive study of the casting, mechanical and special properties of heat-resistant and wear-resistant iron-based alloys in a wide range of chromium concentration, manganese, aluminum, carbon, titanium, and so on, are designed latest heat-resistant and wear-resistant alloys, depending on the specific operating conditions of the cast parts in extreme conditions . It created a database covering more than 600 brands of iron-based alloys, ferro alloys and all existing brands of steel and iron scrap.
