Документ Закономірності формування структурних та механічних властивостей сплава системи Zr-Nb в умовах інтенсивних пластичних деформацій(НТУ "ХПІ", 2013) Злочевська, Н. К.The regularities of formation of the structural properties were determined by deformation in isothermal conditions. The relationship between deformation intensity, structure of material and his mechanical properties was established on the base of experimental forming by the method of helical forging of workpieces, on the base of finite element modeling and metallographic investigation. It was grounded that the plasticity increases at the cost of the refinement of structure components of material.Документ Исследование деформаций металла в местах изгиба при осадке гнутых профилей замкнутого сечения(НТУ "ХПИ", 2013) Забара, Александр СергеевичIn article of deformations in the metal bends with draft tube blank by the finite element method. The analysis of the various schemes of formation. It is concluded that the possibility of modeling of rainfall harvesting, using the finite element method. Set the most appropriate specific conditions and tasks of shaping the way the scheme.Документ Исследование свойств регенерируемых песков(НТУ "ХПИ", 2013) Евтушенко, Наталья СергеевнаThe article investigated the рhysicomechanical properties of regenerated sand for preparation cold-hardening mixes on pitches with oligofurfuriloxysiloxane binding (OFOS) for the manufacture of high-quality castings of ferrous and non-ferrous alloys.Документ Оцінка силового режиму штампування у закритому штампі деталей типу фланців(НТУ "ХПІ", 2013) Євстратов, Віталій Олексійович; Левченко, Володимир МиколайовичThe article is devoted to estimation of power regime of die forging details of burr type in closed impression. Assumed in these work permissions are sufficiently coarse, but even they gives us possibility to estimate the influence of such significant parameters as Dф/D, h/D and α. The analysis is carried out by energetic method.Документ Вихретоковый преобразователь для контроля толщины диэлектрических покрытий на металлоизделиях(НТУ "ХПИ", 2013) Сучков, Григорий Михайлович; Глоба, Светлана Николаевна; Ле, Чи ХиеуThe modification of the compensated eddy current probe (ECP) has been developed, which has a high range of measurement. Experimental researches of ECP performed, which confirmed the promise of its application in the control the thickness of the dielectric coatings on the metal products.Документ Розробка аналітичного методу розрахунку розмірів і форми заготовок для витягування коробчастих виробів(НТУ "ХПІ", 2013) Стеблюк, В. І.; Холявік, О. В.In article provides to the improvement of analytical methods for the calculation of the size and shape of blanks in the drawing box-like parts through the use of the method of building. The experimental and theoretical studies have confirmed the possibility of development of methods for determining the size and shape of pieces in the drawing box-like parts through the use of the method of building and showed a satisfactory correlation between the results obtained experimentally and calculated using the programs developed on the basis of the corresponding models.Документ Пути уменьшения технологической обрези на пилигримовом стане(НТУ "ХПИ", 2013) Стасевский, С. Л.; Угрюмов, Ю. Д.; Гармашов, Д. Ю.; Ксёнз, А. А.The methods of weight reduction pilgrim heads rolling thick- and thin-walled tubes. Industrial research carried out by rolling pipe size 245×10 mm using a special arbor rings providing dokatku pilgergolovki without the cylindrical portion at the rear end of the sleeve. The studies revealed that the savings on a metal sleeve is approximately 30 kg. New technology is being introduced into production for all pipe sizes.Документ Влияние трения на напряженно-деформированное состояние кольца при холодной раскатке(НТУ "ХПИ", 2013) Симсон, Эдуард Альфредович; Scicluna, Steven; Хавин, Валерий Львович; Автономова, Людмила ВладимировнаIt is considered the problem of numerical modeling of cold rolling bearing rings. The resolved equations of mathematical formulation is provided. In the three-dimensional formulation contact problem is solved numerically for different coefficients of friction by using a finite element software DEFORM.Документ Уточненный метод расчета сил, действующих на подшипники рабочих валков станов холодной прокатки тонколистовой стали(НТУ "ХПИ", 2013) Присяжний, А. Г.; Коренко, М. Г.; Сотсков, В. С.The method of calculation of forces, which operate on bearings of workings rollers of the cold rolling mills, is developed in the article. This method allows to determine longevity of bearings of workings rollers taking into account influence of radial and axial forces, the values of which are set depending on all of basic technological factors of process of the cold rolling of thin sheets. Analysis of results of calculation, got on the developed method, expedience of his further application confirms.Документ Пути совершенствования системы управления паровоздушных штамповочных молотов(НТУ "ХПИ", 2013) Попивненко, Л. В.; Ерёмкин, Е. А.; Бочанов, П. А.; Руденко, Н. А.The article deals with a number of advanced schemes of design of system of applied action, which is part of the system of controlling the steam-air stamping hammers . The use of such systems of applied action in modern steam-air stamping hammers would reduce the changeover from one impact to another (from minimum to maximum energy), improve the control accuracy of impact energy and, consequently, the reliability of the most loaded parts and components of hammers .
