Description
Предметом изобретени вл етс индикатор дл регистрации малых деформаций.:The subject of the invention is an indicator for detecting small deformations .:
Известны устройства дл регистрации малых перемещений, в которых при деформации детали измен етс ширина щели, образованной укрепленными па детали иластинкамн, нричем ширина Н1ели определ етс но изменению проход i ; vo через нее светового потока, воснрпннмаемого фотоэлементом.There are known devices for registering small displacements, in which, when a part is deformed, the width of the slit formed by the fortified parts is changed to the elastic band; vo through it the luminous flux, taken by the photocell.
В описываемом индикаторе достигнуто новышеине точности измерени путем применени столь малой П1,ели, что при освещении ее параллелытым нучком монохроматического света на фотопленке, переме цаемой параллельно щели, фотографируетс дифракционна картина.In the described indicator, the new measurement accuracy was achieved by applying such a small P1, which ate, that when it was illuminated with a parallel glass of monochromatic light, a diffraction picture was photographed on the film, parallel to the slit.
На чертеже изображена схема нндикатора.The drawing shows the scheme indicator.
На пснытуемом образце 1 закреилены два пр моугольные угольники 2 и 3, образующие узкую тцель. пмоюн,ую одинаковую игцрпну но всеЛ длине. От источника света 4 через монохроматический светофильтр 5 II линзу 6 на щель направл етс пучок луче1г В результате дифракции скета иа фотоиленке 7, нахо.д щейс за угольниками 2 и 3, иолучаетс дифракционна картппа, характеризуюпщ шприну щели.On the test sample 1, two rectangular squares 2 and 3 are zakreileny, forming a narrow tzel. pmoyun, the same igtsrpnu but all the length. From the light source 4 a monochromatic light filter 5 II lens 6 is directed to the slit by a beam of radiation. As a result of diffraction of the skeleton and photo file 7, located behind angles 2 and 3, a diffraction kartppa is obtained, which characterizes the spacing of the slit.
Фотоплепка 7 движетс нараллольно щели между угольниками 2 и 3. Перед фотопленкой находитс шторка 8 со И1;елью, перпендикул рной иаправлеппю перемещени плойки и вырезаюпде1 узкую иолосу из дифракционной картииы.The photographic splint 7 moves along the gap between the gages 2 and 3. In front of the film there is a shutter 8 with I1; a spruce that is perpendicular to the direction of movement of the curling and a narrow cut out of the diffraction cartium.
