Документ Об исследовании критических скоростей ротора компрессора дизеля 6ТД-2 с нелинейной опорой(НТУ "ХПИ", 2007) Зайцев, Александр Иванович; Шатохин, Владимир МихайловичEstimation method of rotor critical velocities for diesel compressor 6TD subject to bearing nonlinear nature is developed. On the basis of this method lie approaches of initial parameters and harmonic linearization coupled with skeleton curves building idea. The results of design-experiment researches are cited.Документ Методика моделирования трещин с контактирующими берегами на основе метода конечных элементов(НТУ "ХПИ", 2007) Зайцев, Б. Ф.; Шульженко, Н. Г.; Асаёнок, А. В.A technique for calculation of state of stress and strain of cracked bodies taking into account cracks sides contacts in normal direction is proposed. An example of calculation of strains of a cracked shaft under body weight at various shaft angle positions is presented.Документ Исследование вибронагруженности элементов тележек электропоезда ЭПЛ-9Т(НТУ "ХПИ", 2007) Яцько, С. И.; Карпенко, В. В.; Ковалев, А. Е.The questions of definition the vibration load in conditions the ordinary of maintenance of elements of a running part of an electrotrain EPL-9T, manufacture company «Luganskteplovoz» are considered. The dependences of peak and average quadratic values vibration of acceleration, frame of the carriage, bearing assembly and of the electric motor from speed of driving of an electrotrain are obtained. The estimation of influence of electromagnetic perturbations of a drive on results of measurements is given. The obtained datas will be used in designer practice at projection new and operational development of serial elements of a running part of an electrotrain.Документ Восстановление во времени функции нагрузки, воздействующей на бесконечную мембрану-полосу(НТУ "ХПИ", 2007) Янютин, Е. Г.; Кучерова, Н. И.Two methods to solve the inverse problem of determining the unknown time component of load are proposed in the article. It is supposed that the time dependence of deflection of the membrane-belt in one of its points is known. The integral Volterra equations of the first and the second kinds are used to solve the problem.Документ Фильтрация пьезооптических измерений в методе фотоупругости(НТУ "ХПИ", 2007) Тесленко, А. А.In this article the aspects of filtering usage of input and output data of photoelasticity method are investigated by simulation methods. The filtering of data is used together with the finite difference method. Restrictions of the filtration method are found out.Документ Критические состояния консольных упругих труб под действием гироскопических и неконсервативных нагрузок(НТУ "ХПИ", 2007) Соловьев, И. Л.The problem of quasi-static and dynamic buckling of the elastic thin-wall console cylinder tubes rotating under axial non-conservative loading is considered. The dependence of their buckling character from the ratio between the parameter of angular velocity and value of non-conservative loading is investigated.Документ О снижении динамических нагрузок в валопроводе дизеля 6ТД-2(НТУ "ХПИ", 2007) Шатохин, Владимир Михайлович; Шаповалов, А. В.The results of design-experimental research about reasons revealing of dangerous dynamic modes beginnings in diesel drive shafting 6ТД-2 and reduction of their intensities at the expense of springy muff and joining to loads parameter variation are stated.Документ Определение температурных напряжений платы с размещенными на ней электронными радиотехническими элементами(НТУ "ХПИ", 2007) Повгородний, В. О.In this article the temperature stresses for plate with radio-electronic elements are determined. For this purpose the problems of heat conduction and thermoelasticity are solved. Temperature stresses are found by ANSYS complex for rectangular plates. The results are required to make choice of cooling system. These plates with radio-electronic elements and water cooling system are used in the airborne equipment of native airplanes.Документ О стохастической модели статора турбогенератора(НТУ "ХПИ", 2007) Остерник, Э. С.The method for calculating the dynamics of the winding side of embedded stator is offered. This method is based on experiments over the materials of the winding bar and its model. Anisotropy of materials,in-plane shear, wave-like behavior of vibrations, and stochasticity of mechanical properties of materials are taken into consideration. Variational simulation takes into account the actual construction of bar fixing. It allows to evaluate the turbogenerator reliability in the process of operation.Документ Об экстремумах скорости падения сферического тела переменной массы(НТУ "ХПИ", 2007) Ольшанский, В. П.; Ольшанский, Станислав ВасильевичThe extreme properties of vertical fall speed of a spherical body with linearly changing in time radius are investigated. The conditions of motion speed monotonicity are determined.
