Документ Уточнение математической модели ротора на ЭМП за счет определения магнитной проводимости зазоров под полюсами с учетом взаимовлияния смещений в радиальном и осевом направлениях(НТУ "ХПИ", 2006) Мартыненко, Геннадий ЮрьевичIn work the mathematical model of a rotor on magnetic bracket with inclusion in it of the specified nonlinear expressions for permeances of gaps of radial and axial electromagnetic bearing is examined. The example of calculation of permeances of gaps by the offered way and by means of the simplified expressions is describedДокумент Эффективная методика анализа динамических систем с нелинейным демпфированием(НТУ "ХПИ", 2006) Филипковский, С. В.The airplanes aggregates elastic-damped suspensions are reviewed. The efficiency of computational methods of transient analysis of suspensions at an operation on them of short-lived and sudden loads is investigated. Accuracy, convergence and expenses of a machining time in Runge-Kutta, Newmark and Wilson methods are determined . The modifications of Newmark and Wilson methods for calculation of non-linear systems are offered. The calculations of suspensions with constructional dispersion of energy and dry friction are executed. A designed technique and the programs are intended for optimal designing of suspensionДокумент О влиянии управляющих воздействий на динамические нагрузки и параметры поворота гусеничной машины с гидрообъемной передачей(НТУ "ХПИ", 2006) Зайцев, Александр Иванович; Шатохин, Владимир МихайловичModel of caterpillar machine turning, which permits to investigate dynamic processes in engine, transmission with differential mechanisms and hydrovolumetric transmission, running gear as a single whole system, are developed. It takes into account elasticity of connective shaft, road characteristics, object rate of movement, number of transmission, washer of regulable machine control. Results of dynamic processes design-experiment investigations are citedДокумент Один вариант уравнений устойчивости оболочек слоистой структуры с межфазными дефектами(НТУ "ХПИ", 2006) Верещака, Сергей МихайловичOn the basis of the discrete-structural theory of thin shells the variant of the equations of stability of settlement model of multy-layer thin-walled elements with several rigid anisotropic layers is offered. It is considered, that the pressure of cross shift and pressure on border of contact are equal among themselves. It is supposed elastic slipping on a surface of contact of adjacent layers. The permitting equations of stability are received with the account of nonlinear deformations and deformations of cross shift and pressureДокумент Топологически регулярные конечно-элементные сетки для тел с кинематически генерируемыми поверхностями(НТУ "ХПИ", 2006) Ткачук, Николай НиколаевичIn the paper a technology of topological regular finite element models generation for bodies with complicated geometry is proposed. It enables to achieve parameterized finite element models within the framework of researched objects' geometry synthesis procedure and can be implemented in CAE softwareДокумент Автоматизация пьезооптических измерений(НТУ "ХПИ", 2006) Тесленко, А. А.In simulation methods work being presented, the photoelasticity method accuracy is investigated for methods used under measurements automation. Besides, the method application limitations related to the investigated product orientation accuracy evaluation are shownДокумент Математическое и компьютерное моделирование в гидродинамических сложнополостных системах(НТУ "ХПИ", 2006) Суворова, И. Г.; Холобцев, С. С.The mathematic model current of the tough incompressible fluid and her computer realization in POLE system allowed making the numerical research into hydrodynamics canals with compound profile building by R-function method. Qualitative pictures currents are received. The influence of Reinolds number (Re) is valuedДокумент Структурно-механические свойства и морфология биокерамики(НТУ "ХПИ", 2006) Степук, А. А.; Степук, Александр Владимирович; Автономова, Людмила ВладимировнаThe Calcium Hydroxyapatite (HAp), which physical and chemical properties are similar to bone tissue, is applied in various medicine areas as ceramics, cements and composite implants. It is exposed that thermo treatment leads to crystallites form and structure modification. It is examined the crystallites morphology, that influence to structural and mechanical HAp propertiesДокумент Крутильные колебания стержня, вызванные движущейся нагрузкой(НТУ "ХПИ", 2006) Шаповалов, А. В.; Шатохин, Владимир МихайловичPeculiarities of rod torsion oscillations under the influence of equal regularly located on circumference force system are investigated. Force lines of action are perpendicular to circumference plane and rod axle. Points of their application evenly move on stated circumference. Criteria of resonance lack and conditions of polyresonance beginnings are receivedДокумент Выбор допускаемых напряжений в условиях абразивного изнашивания(НТУ "ХПИ", 2006) Приймаков, А. Г.; Устиненко, Александр ВитальевичThe criteria estimation of comparative endurance of materials is given in view of structural adaptation to conditions of a working environment. The level of an anisotropy and complexity of a structural condition of surfaces of abrasive chafing, with the help of the Fourier-assaying is quantitatively estimated. It is shown how to realize a choice of supposed stress at presence of an abrasive in a friction zone
