Description

The object of research is the processes of obtaining products by operations of plastic molding and additive technologies; the purpose of the research is to develop the scientific and technological bases of the processes of materials processing pressure and additive technologies, to develop analytical methods for calculating the stress-strain state, the parameters of form-change and the quality of finished products with the provision of recommendations for the improvement of technological solutions; the research method is a complex of theoretical and experimental-calculation methods for assessing the stress-strain state of materials, the parameters of form-change, temperature deformation conditions and power-supply parameters based on engineering and empirical (approximation) principles and the method of continuum mechanics; Theoretical and practical results - check of mathematical model of process of rolling of hot rolled coils; a methodology and corresponding computer program for estimating the longitudinal stability of the headquarters in the rollers of the SSGP, studying the mechanical properties of 3D printed samples, developed a new water-graphite oil "B-2", analysis of the dependence of the deformation effort on relative deformation during the casting of the fork with the tool on the profiled buoys, the technique of investigations of residual stresses and deformations and determination of the value of springing at bending of sheet blanks; the composition of the lubricant on the water basis is developed; efficiency of implementation - reduction of energy intensity and obtaining high-quality sheet metal rolling on the modern Steckel states, improved stamping of valves of cars, improved grease for hot metal processing; sphere (branch) of use - mechanical engineering, metallurgy.
