The invention relates to a comprehensive experiment device for an opened thin-wall rod piece of an electronic universal testing machine, belonging to the technical field of a constructional engineering experiment. The device comprises I-shaped steel, a loading board, a loading piece, a screw bolt and a screw nail, wherein the loading board is detachably connected with two ends of the I-shaped steel by the loading piece, the screw bolt and the screw nail. The I-shaped steel is taken as an opened thin-wall rod piece, four loading circular holes are respectively designed on wing edges at two ends of the opened thin-wall rod piece, and various combinations of outer force can be realized by converting axial load applied to the electronic universal testing machine by the loading board and the loading piece, so that the aims of uniform stretching experiment, stretching and bending combination experiment, and stretching and twisting combination experiment and teaching can be achieved. The device has the advantages of being capable of realizing various loading experiments, small and exquisite in structure, convenient to adjust, distinct in principle, simple to operate and the like, thereby being widely applicable to a laboratory, an innovative experiment and an engineering simulating experiment of the existing electronic universal testing machine.
Description
Technical field [0001] The invention relates to an open thin-walled bar comprehensive experiment device used for an electronic universal testing machine, which belongs to the technical field of construction engineering experiments. Background technique [0002] Open thin-walled rods are common components and structural forms in engineering, such as I-beams, channel steels, angle steels, etc., and are widely used in steel structure engineering. At present, due to the lack of a multi-functional thin-walled rod experimental device that can realize the combination of tension and bending, and tension and torsion, in experimental teaching and engineering design, we can only focus on its bending performance, and its application in the combination of tension and bending The understanding of the mechanical properties under the combination of tension, tension and torsion is only theoretical, and the lack of experimental verification and analysis not only brings hidden dangers to engin...
