Description

(54) СПОСОБ ОПРЕДЕЛЕНИЯ ДЕФОРМАЦИЙ ЭЛЕМЕНТОВ КОНСТРУКЦИЙ(54) METHOD FOR DETERMINING DEFORMATIONS OF ELEMENTS OF CONSTRUCTIONS

дет фиксировать деформацию раст жени , а другой - деформацию сжати . После установки датчики включают в противоположные плечи измерительного моста и бала сируют . Затем элемент поворачивают на опорах на 180° вокруг оси элемента, чтобы датчики помен лись местам:И. Услови , определ ющие напр женное состо ние элемента, остаютс  при этом без изменений. Полученный после поворота сигнал от тензодатчиков пропорционален удвоенной деформации раст жени -сжати  участка элемента, наход щегос  под базой датчика.It records the deformation of the strain and the other the deformation of the compression. After installation, the sensors are inserted into the opposite shoulders of the measuring bridge and are fitted. Then the element is turned on supports by 180 ° around the axis of the element so that the sensors change places: And. The conditions determining the stress state of the element remain unchanged. The signal obtained from the rotation from strain gauges is proportional to the double tensile strain — compress the portion of the element under the sensor base.

Применение предлагаемого способа позвол ет повысить точность определени  деформаций и упростить методику проведени  испытаний.The application of the proposed method allows to increase the accuracy of strain determination and to simplify the testing procedure.
