specific Embodiment approach

[0018] Such as figure 2 As shown, by placing the sample in the environmental chamber 13, the present invention can test the cyclic deformation behavior of the material in a hot and humid environment. The clamp consists of two flanges (2 and 12), two collet bodies (4 and 10), two reverse buckle nuts (3 and 11), two collets (5 and 9), two pressure caps ( 6 and 8) and so on. The parts are connected as follows:

[0019] The upper flange 2 is tightly connected with the MTS tensile shaft 1 through 8 nuts. The upper flange 2 contains threaded holes, and the upper chuck body contains external threads 19 to be tightly assembled with the threaded holes 14 of the upper flange 2, and the threaded connection between the upper flange 2 and the upper chuck body 4 is fastened by the reverse nut 3, Reduce the influence of thread misalignment in tension and compression cycle experiments. There is a certain slope (17, 20, 21, etc.) at the position where the upper pressure cap 6 and the uppe...

Abstract

The invention discloses an integrated test fixture for circulation, stretch, compression and torsion of advanced materials in hygrothermal environment. The test fixture is composed of an upper flange (2) and a lower flange (12), an upper grip body (4) and a lower grip body (10), two anti-buckle nuts (3 and 11), an upper grip (5), a lower grip (9), an upper pressing cap (6) and a lower pressing cap (8). The test fixture is arranged in a longitudinally symmetrical way. According to the integrated test fixture for stretch, compression, torsion and circulation of various sizes of specimen provided by the invention, not only can tests of stretch, compression, torsion and circulation of various sizes of specimen under hygrothermal environment can be ralized, but also merits of good operability and low cost can be achieved.

Description

technical field [0001] The invention belongs to the field of experimental equipment, in particular to the technical field of manufacturing an integrated test jig for cyclic tension, compression and torsion of advanced materials in a humid and hot environment. Background technique [0002] In recent years, advanced materials such as biomaterials, polymer materials, and shape memory materials have been increasingly widely used in various fields of engineering, and theoretical and experimental research on advanced materials in the field of scientific research is also in full swing. The research on its cyclic deformation behavior in hot and humid environment not only has important scientific research value, but also plays an important role in guiding engineering applications. In order to investigate the cyclic deformation behavior of materials, engineering structural materials are usually processed into specific shapes (such as plates, rods, thin-walled round tubes, etc.), and c...
