Abstract

The invention discloses a novel sheet metal torsion testing machine, which belongs to the field of sheet metal mechanical testing equipment. The novel sheet metal torsion testing machine comprises a frame, a fixing device used for fixing a sheet metal sample, a second fixing device used for fixing the outer rim of the sheet metal sample, and a power apparatus used for driving the second fixing device to rotate by winding the central section of the sheet metal sample; and the first fixing device, the second fixing device and the power apparatus are arranged on the frame. When the novel sheet metal torsion testing machine performs torsion test on the sheet metal sample, wrinkling and friction on the sheet metal sample can be avoided, and the test precision is increased.

Description

technical field [0001] The invention relates to the field of plate mechanics testing equipment, in particular to a novel plate torsion testing machine. Background technique [0002] Most metal sheets will exhibit characteristics such as anisotropy and Bauschinger effect under different loading paths. Conventional standard testing machines can only test the mechanical characteristics of sheets under unidirectional loading conditions (including force-displacement curves, stress-strain curve, etc.). At present, in terms of cyclic loading characteristics, most of the relevant mechanical behavior tests are carried out by using rods. There is no unified plan for the flat panel as the research object because it is easy to wrinkle. [0003] In the existing methods, there is an example of using a fatigue testing machine to perform a cyclic tension-compression test by superimposing multiple plates, but due to the friction between the plates, the accuracy of the test results cannot b...
