Abstract

The invention discloses a tensile test fixture for a ring specimen. The tensile test fixture for the ring specimen is made of low-temperature steel and comprises two tension discs which are opposite and connected movably oppositely; semi-ring grooves are formed in the two tension discs and are arranged oppositely to form a ring groove; baffle assemblies are arranged on the both tension discs and rotationally connected to the edges of the semi-ring grooves corresponding to the tension discs. The fixture is made of low-temperature steel and can be applied to a low-temperature environment; besides, the two opposite tension discs are movably connected oppositely, the semi-ring grooves are formed in the two tension discs, the baffle assemblies rotationally connected are arranged on the tensiondiscs, so that mounting and dismounting of the ring specimen are achieved, the problem of easy sliding in the low-temperature environment is solved, and damage to operators due to ejection of the ringspecimen from the fixture after being broken is effectively prevented.

Description

technical field [0001] The invention relates to the field of tensile testing of low-temperature materials, in particular to a jig for tensile testing of ring specimens. Background technique [0002] With the wide application of composite materials in aviation, aerospace, energy, electrical, chemical, transportation, medical and other fields, it is more and more important to study their mechanical properties in low temperature environment. As we all know, it is extremely difficult to measure the low-temperature tensile properties of composite materials accurately, reliably and stably, which is mainly due to the limitations of the composite materials themselves, such as slippage when the material is stressed at low temperature, and the low temperature environment. due to particularity. [0003] At present, common tensile fixtures are generally complex in structure, large in size, and easy to slip at low temperatures, and are not suitable for use in low temperature environment...
