Abstract
Изобретение относитс к испытательной технике и может быть использовано дл испытани криволинейных образцов на кручение . Цель изобретени - расширение информативности . Два испытуемых образца 4, содержащих закрепленные на их захватных част х по два непараллельных рычага 3, устанавливают симметрично между цилиндрическими поверхност ми нагружающих элементов, каждый из которых выполнен в форме участка кольца 1. Последние располагают попарно в одной плоскости, а их средние части св зывают между собой жесткими св з ми 2. Нагружение образцов 4 осуществл ют при перемещении участков колец 1 навстречу друг другу, что обеспечивает взаимодействие цилиндрических поверхностей последних с соответствующими рычагами 3. В результате при проскальзывании цилиндрических поверхностей участков колец 1 по поверхности рычагов 3 происходит закручивание образцов 4. Использование нагружающих элементов в виде участков кольца с радиусом кривизны, равным радиусу кривизны образцов, позвол ет испытывать образцы различного радиуса кривизны, что расшир ет информативность способа. 5 ил. :л ь сThe invention relates to a testing technique and can be used to test curved torsional specimens. The purpose of the invention is the expansion of information content. Two test specimens 4, containing two non-parallel levers 3 fixed on their gripping parts, are placed symmetrically between the cylindrical surfaces of the loading elements, each of which is made in the form of a portion of the ring 1. between each other by rigid connections 2. Samples 4 are loaded when moving sections of rings 1 towards each other, which ensures the interaction of the cylindrical surfaces of the latter with the corresponding p Legs 3. As a result, when the cylindrical surfaces of the sections of the rings 1 slip along the surface of the levers 3, the samples 4 are twisted. . 5 il. : ls with
