Full textЗащищаются результаты теоретических и экспериментальных исследований по важной научно-технической проблеме - повышение информативности геолого-геофизических исследований пород-коллекторов полимиктового типа каменноугольных и пермских отложений центральной части Днепровско-Донецкой впадины. Неоднородность минералогического состава пород-коллекторов каменноугольных и пермских отложений их полимиктовость, а также недостаточная информативность комплекса методов геофизических исследований скважин затрудняет интерпретацию результатов ГИС, снижает эффективность геолого-геофизических поисковых работ. Наличие в породах-коллекторах полевых шпатов и слюд влияет на их физические свойства, усложняет применение методик выделения полимиктовых песчаников в геологическом разрезе. Обобщение и анализ результатов лабораторных и скважинных исследований позволили выявить особенности распределения иородообразующих и акцессорных минералов в породах-коллекторах полимиктового типа и на их основе разработать петрофизические взаимосвязи типа “керн-керн”, “керн-геофизика”. За данными лабораторных гамма-спектрометрических исследований разработана методика по выделению полимиктовых песчаников, которая основана на использовании информации распределении калия и тория в породах как мономиктового, так и полимиктового типа. Используя результаты лабораторных гамма-спектрометрических исследований кернового материала, а также данные скважинных геофизических исследований полимиктовых пород нами разработаны методики литологического расчленения геологического разреза, определения глинистости за данными радиоактивного каротажа и гамма-спектрометрии, способы интерпретации данных импульсного нейтрон-нейтронного каротажа. В результате проведённых работ разработано схему комплексных геолого-геофизических исследований полимиктовых пород-коллекторов каменноугольных и пермских отложений центральной части ДДЗ, которую можно использовать и в других регионах Украины.

The influence of the depth of the grid of the upper level of the grounding devices of the substations, the thickness of the humidification layer, the drying or freezing of the soil and the design of the grounding devices on its electrical characteristics was studied. Based on the theoretical substantiation of the method, a technique for measuring the resistance of grounding devices of substations in conditions of dense building of the territory is developed.

Full textThe thesis in qualification for a scientific degree of Candidate of Technical Science in speciality 05.02.09 ‒ dynamics and strength of machines, National Technical University "Kharkiv Polytechnical Institute", Kharkiv, 2018. The dissertation deals with the development of approach and models for providing of structural strength of complicated thin-walled machine-building structures, which operate in the conditions of geometric and physical nonlinearities using design solution validation. The developed approach is based on the use of mathematical model for stress-strain state taking into account geometric and physical nonlinearities and methods of approximation for constructing functions describing the evaluated characteristics of the object under study. The various factors behind the search for design solutions (including characteristics of strength, rigidity, technological and economic factors), are being added into this function. During searching for design solutions it is proposed to successively use approximation models of various accuracy degrees. The developed algorithm for rational parameters search, which takes into account the peculiarities of the response surface shape observed in solving applied problems, is applied to them. In this case, the solution is sought over the whole range of parameter changes. Thus, in the search process, global trends of changes in design decisions are taken into account, and not local ones, as in other approaches. This allows obtain a rational solution that is stable to changes in parameters, which are possible in course of design work and production conditions. The developed algorithms and models are used for solving test and applied problems. In particular, recommendations for the body framing of the bus, freight car, the frame of the tractor cabin, the BTR-80 and MT-L hulls are developed. Computational and experimental verification of developed finite-element models was carried out. The research was carried out at three objects: on the upper part of BTR-80 armored personnel carrier mock-up, and on the prototypes of BTR-3E hull and covered railcar. During frequency characteristics studies, the oscillations excitation of the hull mock-up was effected by rubberized drummer influence at certain points of structure. With use of verified finite element models, the BTR-3E hull prototype was investigated. The experimental research technique provided impulsive action on the hull at a number of points, and fixation of time distributions of accelerations at these points by accelerometers. The results difference is in range of 8-12% for frequencies of free oscillations and for damping logarithmic decrement. Computational studies, and then full-scale tests are also subject to the covered railcar prototype made with recommended settings. Average difference for displacement and stress is 15%.

Full textThe thesis is submitted to obtain a scientific degree of Doctor of Philosophy, specialty 141 – Electricity, electronics and electrical engineering – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2020. The object of research are inductors of rotating magnetic field for technological operation of various substances. The subject of research are electromagnetic parameters and characteristics of inductors of rotating magnetic field. The dissertation is dedicated to solve actual scientific task of the design analysis development of electromagnetic parameters and characteristics of rotating magnetic field inductors for various substances technological operation. The introduction substantiates the relevance of the research tasks, shows the relationship of the work with scientific programs, plans, themes, provides scientific novelty and the practical significance of the results was formulated. In the first section, it is established that the existing methods for designing rotating magnetic field inductors based on the stator of a three-phase asynchronous motor are based on calculations of the magnetic field in the ideal idle mode and do not use numerical methods, which, as presented in the thesis, allow calculating the characteristics of the inductor in the load mode at the presence of ferromagnetic elements in its working chamber and give significant progress in the possibilities of designing and improving their design. The second chapter shows that the application of the quasi-three-dimensional mathematical model of the inductor, that was based on the method of plane-orthogonal calculated models, that combines the magnetic fields of the transverse and longitudinal sections of the inductor, allows us to analyze the distributions of magnetic induction in the transverse and longitudinal sections and to show fully its three-dimensional character. Based on the numerical-field calculations of rotating magnetic field the calculation methodology was presented in order to analyze the effect of shortening the stator winding of the inductor on its electromagnetic parameters. The proposed calculation methodology of the magnetic loss power based on the RMS maximums value of the magnetic induction module, that turned out to be universal from the point of view various geometric shapes of the toothed-groove structure and the stator yoke, because it doesn't need require simplifications of the design models geometry of these parts of the construction design. The third chapter deals with the inductor load angle that corresponds to the angle of rotation of the magnetic field and it was defined for the first time, but turns out that the inductor load angle two times less than the phase angle of the inductor winding currents. It turns out that the period of the angular torque characteristic two times less than the period of the inductor winding currents, which corresponds to the classical ideas about the angular functions of the reactive torque of electrical machines. Eventually, it allows to classify the considered inductor, together with the anisotropic magnetic environment in the working chamber, to the class of reluctance synchronous machines, and specifically, motors. The accounting method of the magnetic anisotropy of the inductor working chamber in dependence to concentration of ferromagnetic elements in it was proposed. It allows to obtain a mathematical model for determining the quantitative and phase correlations of its electromagnetic values in the load mode: magnetic induction, magnetic flux linkage, EMF, current voltage of the stator winding, and the electromagnetic torque in the working chamber. The presented methodology which is based on numerical calculations of magnetic fields, allows organizing an iterative process for the computational analysis of the characteristics of the inductor, that operates with a variable load at a stable current or supply voltage of its winding. By the test calculations it was found, that in the area of constant operation in terms of energy, the inductor is characterized by a sufficiently high efficiency and a very low power factor. During the comparison of the inductor angular characteristics, it was found that the more rational for the inductor working is the voltage stabilization mode, which in the desired working range of the load angle up to 25° provides the best electrical, magnetic, power and energy parameters. The current method for monitoring the concentration of ferromagnetic elements in the working chamber of the inductor during its operation was proposed. The practical calculations have shown that this method is more sensitive and doesn't require a complication of the inductor design in comparison with the alternative monitoring method using measuring coils. Observing the winding current of the inductor allows us to control the filling with ferromagnetic elements of its working chamber without interrupting the working process. It allows to replenish the working chamber in time with such elements and thereby maintain the technological operation of various substances on a given level, which are passed through this chamber. In the fourth chapter experimental studies of the inductor physical model are presented and it confirmed the results of mathematical modeling of the electromagnetic processes of the inductor in the no-load mode and in the operate mode.

Full textThe work is devoted to the study of the dependence of the vital capacity of the lungs of students of Ukrainian free economic zones on the way of life and external factors. The vital capacity of 224 students of three Ukrainian higher education institutions was studied. It was found that the majority of students have an unsatisfactory level of VL (48.7%), a satisfactory level - 40.6% and 10.7% of those who have a sufficient level. According to the results of the study, it was determined that the most decisive influence on the value of vital capacity of students' lungs are age, sex, as well as features of their lifestyle (including physical activity, smoking) and air pollution. The positive effect of vocal training on the value of vital capacity of the lungs is proved.
