Abstract
Изобретение относитс к области испытательной техники, к устройствам дл нанесени усталостной трещины. Цель изобретени - расширение функциональных возможностей путем обеспечени нанесени трещины как на цилиндрический образец, так и на образец с иной формой поперечного сечени . Образец 1 консольно закрепл ют в захвате, привод т во вращение. Нагружатели 3 через упругий элемент 5 и обойму 2 передают посто нную перерезывающую силу, что приводит к росту трещины из концентратора 7. 1 ил.The invention relates to the field of testing equipment, to devices for applying fatigue cracks. The purpose of the invention is to enhance the functionality by ensuring that a crack is applied to both the cylindrical specimen and the specimen with a different cross-sectional shape. Sample 1 is cantilevered in the gripper and rotated. Loaders 3 through the elastic element 5 and the holder 2 transmit a constant shear force, which leads to the growth of a crack from the hub 7. 1 Il.
Description
Изобретение относится к испытательной технике, а именно, к устройствам для нанесения усталостной трещины.The invention relates to a testing technique, namely, to devices for applying a fatigue crack.
Цель изобретения- расширение функциональных возможностей путем обеспечения нанесения трещины как на цилиндрический образец, так и образец с иной формой поперечного сечения.The purpose of the invention is the expansion of functionality by ensuring the application of cracks on both a cylindrical specimen and a specimen with a different cross-sectional shape.
На чертеже представлена схема устройства.The drawing shows a diagram of the device.
Устройство состоит из жестко насаженной на консольно закрепленный образец 1 обоймы 2, цилиндрическая поверхность которой взаимодействует с нагружателем 3. Нагружатель 3 содержит шарик 4 и упругий элемент 5, натяг которого устанавливается регулировочным винтом 6. Захват образца связан с приводом вращения.The device consists of a cartridge 2 rigidly mounted on a cantilever-mounted sample 1, the cylindrical surface of which interacts with the loader 3. The loader 3 contains a ball 4 and an elastic element 5, the tension of which is set by the adjusting screw 6. The sample is connected to the rotation drive.
Устройство работает следующим образом.The device operates as follows.
На границе концентратора закрепляют обойму 2, приводят в контакт нагружатель 3 с обоймой 2 и приводят во вращение образец. При этом трещина развивается из концентратора 7.At the boundary of the concentrator, a ferrule 2 is fixed, a loader 3 is brought into contact with a ferrule 2, and the sample is rotated. When this crack develops from the hub 7.
