Сенсорные микросистемы на поверхностных акустических волнах
(БНТУ, 2004)The most promising tendency in development сенсорики represents mining of intelligent sensor} microsystems (ISMS) on the basis of integf-ating sensory, processor and actuators. At present work the problems ofdesigning ISMS with SA W with frequency band 100 MHz — 2 GHz conforming to dimensional area of technology micro and a nanoelectronics and the microelectromechanics are ...2020-06-15 -
Дисперсионные зависимости поверхностных акустических волн в структуре LilNbO,/a:C
(БНТУ, 2004)From the point ofview the microelectromechanics the surface acoustic waves (SA W) in multilayer structures consisting of a crystalline substrate and several parallel plate functional layers of different thickness from crystalline, polycrystallic, nanostructured or amorphous materials. One of the most perspective material of a SAW substrate is the single-crystal lithium niobate ...2020-06-15 -
Методика использования САПР для исследования механических систем
(БНТУ, 2004)Scientific investigation of mechanism is impossible without mathematical modeling. CAE software i the best tool for simulation of complicated dynamical system’s behavior. The idea of designer’s universi work place is formulated. Agricultural vehicle suspension with hydropneumatic springs was designei Suspension designing and all necessary calculations were performed using CAD/CAE ...2020-06-15 -
Моделирование волновых движений в кубически анизотропных средах на базе метода характеристик
(БНТУ, 2004)The expressions for velocities of propagation of elastic waves are obtained, and also for coordinates of points of cubic anisotropic medium, up to which the wave perturbation has reached. With their help the wave surface and surface of inverse velocities of quasitransversal waves is constructed.2020-06-15 -

Связанность теплового и механического полей в динамических задачах в напряжениях для изотропных и анизотропных сред
(БНТУ, 2004)On the equations of weak disruptures for combined equations of a motion isotropic and cubic anisotropic mediums noted in builders of a stress tensor, the expressions for coefficients of a connectedness of mechanical and thermal fields are obtained. Is shown, that at magnification of dimensionality of a problem (on spatial coordinate) the values of coefficients of a connectedness ...2020-06-15 -
Использование СУБД в расчетах упругих задач методом конечных элементов
(БНТУ, 2004)The method of finite element is widely used in different engineer calculations. The basic correlations are in the matrix form; it allows to use some Control Data Base Systems to solve these tasks. In this research work we made the special interface and main program; also we’d like to note the way to enter and edit the input data.2020-06-15
