ИССЛЕДОВАНИЕ ВЕЛИЧИНЫ ДЕФОРМАЦИИ, НАПРЯЖЕНИЙ И СОБСТВЕННЫХ ЧАСТОТНЫХ КОЛЕБАНИЙ ЗВЕЗДНОГО ДАТЧИКА ПРИ ЭКВИВАЛЕНТНОМ ИНЕРЦИОННОМ НАГРУЖЕНИИ

The 3D-model of the star sensor was design in the Pro/ENGINEER program. Mechanical analysis of rigidity of the construction was carry out in MSC Patran program. The value of the deformation and equivalent stress by gravitation 1g and 30g for loading by axis X, Y, was carry out. Account of self frequency in range of 200 to 6000 Hz was compute, and for the first 10 modes were received shapes of oscillation of the device. В среде САПР Pro/ENGINEER создана трехмерная модель звездного датчика, посредством программного пакета MSC Patran проведен механический анализ жесткости конструкции изделия. Определены величины деформаций и эквивалентных напряжений при инерционных нагрузках под воздействием гравитации 1 g и 30 g для нагрузки по осям X, Y и Z. Проведен расчет собственных частот колебаний в диапазоне от 200 до 6000 Гц и для первых 10 мод получены формы колебаний изделия.
