Abstract
Изобретение может быть использовано дл определени прочностных характеристик материалов трубчатых образцов. Цель изобретени - повышение точности путем создани в образце равномерно распределенной нагрузки. На концах образца 3 устанавливают кольца 4 и 5, выполненные из высокопластичного материала, и обжимают их при помощи полуколец. На равном рассто нии от концов образца 3 размещают рабочий элемент 11, что при сжатии его штоками 12 и 13 обеспечивает нагружение средней части образца 3 равномерно распределенным усилием, создающим при обжатых концах образца 3 условие чистого изгиба его стенок от внутреннего давлени . Длина рабочего элемента 11 выбрана от 1 до 3 внутренних диаметров образца 3, что обеспечивает однородное напр женное состо ние рабочего элемента, а следовательно, равномерно распределенное давление по внутренней поверхности образца 3. 2 ил.The invention can be used to determine the strength characteristics of materials of tubular specimens. The purpose of the invention is to improve the accuracy by creating a uniformly distributed load in the sample. At the ends of sample 3, rings 4 and 5, made of highly plastic material, are installed and compressed using half rings. Equal distance from the ends of sample 3, the working element 11 is placed, which, when compressed by rods 12 and 13, provides loading of the middle part of sample 3 by uniformly distributed force, creating, at the ends of sample 3, the condition of clean bending of its walls from internal pressure. The length of the working element 11 is selected from 1 to 3 internal diameters of the sample 3, which ensures a uniform tension state of the working element, and therefore, uniformly distributed pressure on the inner surface of the sample 3. 2 Il.
