Документ Начальное деформирование упругого полупространства при кинематическом воздействии(НТУ "ХПИ", 2013) Янютин, Е. Г.; Богдан, Д. И.; Толбатов, Евгений ЮрьевичThe elastic oscillations of a half-space in case of the kinematical influence set on its surface are described in the article. Nonaxisymmetric statement of the second boundary value problem is considered. The problem is solved by using of expansion in Fourier series. The numerical example on finding of movings on depth of the half-space is considered at the known kinematical impact on it's surface.Документ Перспективы применения импульсных струй жидкости для тушения газовых факелов(НТУ "ХПИ", 2013) Семко, А. Н.; Бескровная, М. В.; Украинский, Ю. Д.; Виноградов, С. А.; Грицына, И. Н.Experimental studies of putting out of gas blowout by means of high-speed impulse liquid jets generated by a powder pulse-jet water canon have been carried out. The speed of impulse jet depending on charge energy ranged in the experiments from 300 to 600 m/s. The speed of the head section of the jet has been measured directly before the torch by means of a non-contact laser speed measuring device, the jet photographing has been carried out. It has been shown that around the high-speed liquid impulse jet in the air is formed a high-speed cloud of large cross-section splashes that efficiently knocks down the flame of the gas torch at distances of 5-20 m from the unit.Документ Моделирование течения крови в патологически искривленных сосудах(НТУ "ХПИ", 2013) Оверко, В. С.; Бескровная, М. В.Mathematical simulation of the blood flow in the pathologically curved blood vessels was performed. Influence of degrees of the curvature by the intensity and the features of the secondary and the reverse blood flow in the vessels at different times cardiac cycle was determined. The loss pressure for different level of the pathological curvature was defined.Документ Функция Ламберта в задаче баллистики материальной точки(НТУ "ХПИ", 2013) Ольшанский, В. П.; Ольшанский, Станислав ВасильевичIt is shown that the use of the Lambert function and tables greatly simplifies the calculation of range and other parameters of the trajectory of the motion of a particle in a gas medium with a linear resistance.Документ Умови формування пружних переміщень у технологічній системі при механічній обробці(НТУ "ХПІ", 2013) Новіков, Федір Васильович; Іванов, І. Є.The paper offers a theoretical approach to the calculation and analysis of the accuracy of processing parameters with the elastic displacements occurring in the technological system. On the basis of the theoretical results obtained implementing the conditions for the best possible performance for a given precision machining machined surface. Practical recommendations for the effective management of the cutting process.Документ Математична модель визначення шорсткості поверхні при абразивній обробці(НТУ "ХПІ", 2013) Новіков, Федір Васильович; Нежебовський, В. В.; Шкурупій, Валентин ГригоровичThe results of theoretical studies of the formation of surface roughness during abrasive machining. The classification structures of the rough surface layer. The basic terms of reducing the surface roughness and practical recommendations for the effective implementation of methods of abrasion.Документ Дослідження робочого процесу вихрового ступеня за допомогою обчислювального експерименту(НТУ "ХПІ", 2013) Ніколаєнко, Людмила Михайлівна; Лугова, Світлана Олегівна; Салтанов, Станіслав Ігоревич; Котенко, Олександр ІвановичIn this article the analysis of existing methods of calculation of the characteristics of the vortex stage. With the use of the software product of ANSYS CFX 12.0 is a numerical study of the flow in the liquid part of the vortex stage of open type with side channel for a different number of blades, received by the flow pattern and the integral characteristics of the vortex extent.Документ Дослідження системи управління вібраційним об'єктом(НТУ "ХПІ", 2013) Мигущенко, Руслан Павлович; Кропачек, Ольга Юріївна; Семенченко, Анастасія Сергіївна; Матяш, Катерина ВолодимирівнаThe paper deals with the construction management industry vibrating object. In order to develope the control system chosen object of study, the analysis of its operation, reviewed and analyzed the possible models under consideration of the objects elected in the major areas of research.Документ Оцінка ефективності інформаційної технології предметно-орієнтованого математичного моделювання(НТУ "ХПІ", 2013) Межуєв, В. І.The evaluation of effectiveness of the Information Technology of Domain-Specific Mathematical Modeling (ITDSMM) is given. The reduction of amount of operations needed for development of metamodels in the case of using ITDSMM is proven. The optimization task of choosing the most effective information technology by selection and comparison of the multiple features in herent to the DSM, DSMM and UML technologies is solved.Документ Сравнительный анализ двух подходов к исследованию параметрических колебаний ортотропных пластин сложной формы(НТУ "ХПИ", 2013) Мазур, Ольга СергеевнаParametric vibrations of the orthotropic plates with complex form and various boundary conditions are studied by two approaches. The first method uses the movement equations in terms of displacements; the second approach is based on using the equations in mixed form. The results obtained by the presented algorithms are compared for T-plate.
