Документ Упрощение модели ошибок инерциальной навигации при различных видах движения летательного аппарата(НТУ "ХПИ", 2006) Успенский, Валерий Борисович; Багмут, Иван АлександровичTo research observability of tool errors of sensitive elements strapdown inertial navigating system without simplification of initial model of errors of strapdown inertial navigating system it is practically impossible. At the same time there is an assumption, that at the certain maneuvers of the air flying device, corresponding errors of sensitive elements can be neglected and therefore will be possible to receive much more simple models of errors of strapdown inertial navigating system. Therefore represents practical interest to receive the simplified models of errors of strapdown inertial navigating system suitable for the subsequent analysis tool errors of sensitive elements observabilityДокумент Некоторые подробности применения метода конечных элементов в фотоупругости(НТУ "ХПИ", 2006) Тесленко, А. А.Bases of a new modification of photoelasticity method and possibility of its model research are examined in work. Essence of a new modification consists of combination of possibilities of traditional photoelasticity method and finite-element method. Estimation of influencing of exactness of setting of the explored body on exactness in determination of tensions in the conditions of particular matter and chart of measuring is produceДокумент Расчет термонапряженного состояния многослойных пластин неканонической формы в плане(НТУ "ХПИ", 2006) Сметанкина, Н. В.; Свет, Е. В.; Шупиков, А. Н.A method for solution of a stationary termoelasticity problem of multilayer plates of non-canonical plan form which contour formed by straight lines and arches of circles is offered. Thermal loadings are obtained as result of solution of multilayer plate heat conduction problem. Thermal stresses in a five-layer plate are analyzedДокумент Динамические характеристики систем с поворотной симметрией при нерегулярной вариации параметров(НТУ "ХПИ", 2006) Симсон, Эдуард Альфредович; Назаренко, Сергей Александрович; Белозеров, А. В.Complicated finite-element models of cyclic symmetry structure with high geometric and physical self-descriptiveness sensitivity analysis and optimization methods are given in this article. Тю methods have guiding to orientate on high dimensions of state and design variables. Computation stages of constructions gradients functional derivation are investigated. Тю developed mathematical apparatus application domains are examinedДокумент Приближенное определение нестационарного температурного поля в цилиндре конечной длины(НТУ "ХПИ", 2006) Пустовалов, Владимир Николаевич; Навроцкий, В. В.; Михайленко, Т. И.The approximate solution of non-steady thermal conductivity for the final dimension cylinder is resulted. The method of solution is related to transition in the axis-symmetryс differential solution to new variable as the overall integral value of temperature. Comparative computations of exact and approximate decisions testify to sufficient efficiency and convenience of method for practical computationsДокумент Експериментальне дослідження працездатності колінчастих валів та циліндро-поршневих груп дизелів авіаційної наземної техніки(НТУ "ХПІ", 2006) Приймаков, Олександр Григорович; Градиський, Юрій ОлександровичIn this article there are results long-term tests of diesel engines of the aviation ground technique. It has the purpose of determination of supply of operating properties that provide efficiency and reliability of details and assembling units within the limits of guarantee workДокумент Исследование надежности приборного блока самолета по виброускорениям(НТУ "ХПИ", 2006) Повгородний, В. О.In this article are introduced number's index of the fail-safe including vibration accelerations, free frequences and thermal stresses. The problem is soluted by the finite element's method and method of the theory of throw outs. The results for the new device of aircraft, which introduce the pocket of plates with electronical radiotechnical elementsДокумент Моделирование процессов накопления повреждаемости в тонких пластинах при действии ударных нагрузок(НТУ "ХПИ", 2006) Онищенко, А. В.The paper is devoted to the investigation of damage accumulation in thin plate with constant thickness, which is under impact loading. The single impact is presented in the one cycle. The linear damage summation is considered. The impact problem on the each cycle is solved by numerical-iterative method: the impact force value was found by use of finite difference scheme, the deformed plate state was determined analytically by shear Timoshenko's theory. The numerical examples are givenДокумент Эффект отражения мелкодисперсных испаряющихся капель встречным потоком газа(НТУ "ХПИ", 2006) Ольшанский, В. П.; Ольшанский, Станислав ВасильевичThe movement of a drop is considered which evaporates, as material point of variable weight. In the assumption, that the force of aerodynamic interaction of a drop with gas environment is proportional to a square of speed of a flow, the approached analytical decisions of the nonlinear differential equations of movement are received, in special functions. The effect of reflection of a drop is investigated, that is change of her direction movement, counter gas flow is exacterДокумент Длительная прочность диска турбины(НТУ "ХПИ", 2006) Морачковский, Олег Константинович; Соболь, Владимир НиколаевичThe problem statement and solution method of creep-damage lifetime prediction for the turbine disk are presented in the paper. The creep-damage calculation results for the disks with constant thickness and variable section are given in the various time moments. The influence analyses of the disk section form on the rupture time have been done
