Изобретение относитс к измерительной технике, в частности к способам градуировки тензорезисторов.The invention relates to a measurement technique, in particular to methods for calibrating strain gauges.
Цель изобретени - повышение точ- ности измерени деформаций консольной тензобалки равного сечени в зоне наклейки градуируемого тензорезистора.The purpose of the invention is to improve the accuracy of measuring deformations of a cantilever tensioner of equal cross section in the area of gluing of a graduated strain gauge.
На чертеже представлена схема реализации предлагаемого способа. The drawing shows the implementation of the proposed method.
На чертеже обозначено: 1 - градуи- ровочна консольна тензобалка равного сечени ; 2 - градуируемый тензоре- Зистор; Р - воздействующа нагрузка; JL и h - длина и толщина тензобал- ки; f - прогиб тензобалки в точке d при нагружении I и в точке с при на- Гружении II; а-координата фиксированной точки с.In the drawing it is indicated: 1 - graduated console load-work roller of equal section; 2 - graduated tensor-Zistor; P - acting load; JL and h are the length and thickness of the strainer; f is the deflection action deflection at point d under load I and at point c under loading I; a-coordinate of a fixed point
Способ осуществл ют следующим об- разом.The method is carried out as follows.
Измер ют длину 1 и толщину h ненагруженной балки с наклеенным тензо- резистором 2. 5чтем балку 1 дважды (нагружают: первый раз - до получе- :ни прогиба f, который измер ют, в точке d, а второй раз - до получени такого же прогиба f в фиксированной точке с, отсто щей от конечной точкиMeasure length 1 and thickness h of an unloaded beam with a glued strain resistance resistor 2. 5 so the beam 1 twice (load: the first time to get: no deflection f, which is measured at point d, and the second time to get the same deflection f at a fixed point with a distance from the end point
d на рассто нии а. При первом и втором нагружени х фиксируют соответственно изменени сопротивлени градуируемого тензорезистора uR, и uR. Градуировочную деформацию 6, балки в зоне наклейки тензорезистора при первом нагружении определ ют по формулеd at a distance a. During the first and second loads, the changes in the resistance of the calibrated resistance strain gage uR and uR are recorded, respectively. The calibration deformation 6, the beams in the area of the gage of the strain gauge at the first loading is determined by the formula
