Abstract

Использование: проведение прочностных испытаний на раст жение образцов деталей, изготовленных из различных материалов . Сущность изобретени : на основании 1 устройства дл  испытани  на раст жение установлен нагружатель 2. Две упругие мембранные пластины: повышенной жесткости 3 и малой жесткости 4, жестко св занные с нагружателем, установлены параллельно друг другу и жестко закрепле ны по контуру на неподвижных опорах осно вани  5 и 6 соответственно, ФланЦы 7 и 8 дл  креплени  захватов 9 и 10 концов Образца к мембранам расположены в их центре, 2 илUse: conduct tensile strength tests on specimens of parts made from various materials. The invention: on the base 1 of the tensile tester, a loader 2 is mounted. Two elastic membrane plates: of increased rigidity 3 and of low rigidity 4, rigidly connected to the loader, are installed parallel to each other and rigidly fixed along the contour on the fixed supports of the base 5 and 6, respectively, flanges 7 and 8 for fastening the grippers 9 and 10 of the Sample ends to the membranes are located in their center, 2 silt

Description

где APi - нагрузка, воспринимаема  мемб- ранноР пластиной повышенной жесткости при прогибе ЛИ, с другой стороны, это нагрузка , передаваема  через образец, т.е. APi Робр.where APi is the load perceived by the membrane with a plate of increased rigidity during LIE deflection, on the other hand, it is the load transmitted through the sample, i.e. APi Rob.
