Документ Анализ напряженно-деформированного состояния шейного отдела позвоночника при ортезировании различными видами ортезов(НТУ "ХПИ", 2013) Веретельник, Олег Викторович; Ткачук, Николай Анатольевич; Барыш, А. Е.; Тимченко, И. Б.; Дынник, А. А.; Погорелая, А. В.This paper presents the results of numerical studies of the mechanical behaviour of the cervical spine with the use of orthesis. Participate in the examination of five different types of orthesis construction as the outer form, and on the materials from which they are made.Документ Совершенствование методов расчета элементов машин с длительным сроком работы при действии многокомпонентной загрузки с учетом их утонения(НТУ "ХПИ", 2013) Васильева, Т. А.; Теплицкий, Л. Л.This paper describes a new approach to justification of parameters of machines elements designed for along term of work under the influence of multi-component loads taking into account their thinning during work. It's proposed to consider the combined effect of different types of loads to determine the resource of machines elements. It is suggested also to take into account the change of effective thickness, that takes place by the end of term of exploitation. Examples of the use of proposed approach to the analysis of frames of locomotives are presented.Документ Обоснование расчетных моделей силосных установок(НТУ "ХПИ", 2013) Третьяков, В. Б.; Иванцов, И. И.; Веретельник, Олег Викторович; Атрошенко, Александр АлександровичThis paper describes the results of research of the stress-strained state of a silage for storage of grain and other products. Test problems are considered for corrugated panel's silage for bolted connections, as well as full body design silage. Described the problematic factors for building computational models of the elements of silage.Документ Разработка математической модели червячной пары для производства червячных передач на универсальных обрабатывающих центрах(НТУ "ХПИ", 2013) Стрельников, В. Н.; Суков, Г. С.; Воробьев, Н. Д.; Суков, М. Г.; Нечепоренко, И. Ю.; Гавриш, Ю. П.; Чеченец, В. Н.; Донской, Д. И.On the basis of the theory of synthesis of spatial meshings the mathematical model of worm pair a general view on axial section of a coil of the worm which profile is set by any smooth curveis developed. For improvement of working conditions and qualitative parameters of the worm gear, the interfaced surfaces organizeis convex-concave contact of nearest curvature. The operating program developed on the basis of created mathematical model, boots in NC-system the universal treating centre for generation of a worm and gear working surfaces.Документ Распределение контактных давлений при контакте тел конечных размеров по поверхностям близкой формы(НТУ "ХПИ", 2013) Скрипченко, Наталья БорисовнаFor a case of contact of bodies with close curvature radiuses along one of main directions general statement of contact task is offered. Functions of contact pressured is tribution, maximal contact pressure, and also lengths of contact spot semiaxes are got by analytical and numerical methods.Документ Особенности распределения контактных давлений в сопряжении деталей с дискретным упрочнением(НТУ "ХПИ", 2013) Шеремет, В. Н.; Веретельник, Олег Викторович; Литвин, Б. Я.; Шейко, А. И.; Кравченко, Сергей АлександровичIn the paper results are described for research of features of stressed-deformed state at contact interaction of details which surfaces are discretely strengthened. The substantial irregularity of contact pressure distribution is detected on contact surface.Документ Исследование периодических погрешностей и их природы при анализе достоверности математической модели для исследования динамических характеристик механизма(НТУ "ХПИ", 2013) Сериков, Владимир ИвановичIn the paper a method is founded and described for sampling data collected during a series of experiments and fixed on photo paper with K-12-22 loop oscillograph. Received numerical data have allowed not only to estimate correctness of chosen mathematical model, but also to clarify the nature of error periodic vibrations.Документ Обоснование необходимости автоматизированного контроля реологических параметров высоковязкого топлива при сепарировании(НТУ "ХПИ", 2013) Радченко, О. П.; Мацкевич, А. Р.; Неменко, А. В.; Чуб, О. П.Considered the issues of necessity of automation and control of the process of separation of viscosity marine fuel. Obtained dependence of the particle separation of sludge from the temperature on the basis of theoretical concepts, the results of their comparative analysis of the evidence.Документ Математическое и численное моделирование динамических процессов в элементах легкобронированных боевых машин(Национальный технический университет "Харьковский политехнический институт", 2013) Мельник, Б. А.; Малакей, Андрей Николаевич; Мухин, Дмитрий Сергеевич; Танченко, Андрей Юрьевич; Кохановская, Ольга ВладиславовнаIn the paper questions of complex modeling of dynamic processes in elements of lightly armored fighting vehicles are expounded. The complex mathematical model of disturbed motion is built taking in to account variable parameters of pendant of wheeled fighting vehicles. Results of test numerical modeling of dynamic processes are presented on example of armored hull and pendant of BTR-80 armored troop-carrier.Документ Комплексные экспериментальные исследования динамических характеристик фрагментов, макетов и натурных образцов элементов бронекорпусов транспортных средств специального назначения(НТУ "ХПИ", 2013) Литвиненко, А. В.Complex experimental researches of fragments, prototypes and full-scale models of armored hulls of lightly armored vehicles are described. These results are forming the data base of comparative computation and experimental researches. Their aim is grounding of reliable, complete and exact created numerical models of elements of armored hulls of special transport vehicles for realization of project researches of their vibrations and stressed-deformed state. Methods of vibro-accelerometers, electrical tensometry and holographic interferometry are applied.
