Abstract
The invention discloses a tension-torsion testing machine applicable to measurement for all characteristic parameters of the tension and the torsion of a material and a testing method thereof. The tension-torsion testing machine comprises a machine body, wherein a transmission device is arranged in the machine body; a frame is arranged at the upper part of the machine body; the connecting position between the machine body and the frame is provided with a first connecting plate; a lifting device is arranged in the frame; the transmission device drives the lifting device to rise and fall. The testing machine has the characteristics that after speed reduction by a worm wheel and worm, a middle bevel gear is driven to rotate by transmission of a middle shaft, so that the rotation of a lower chuck is finished; bevel gears at two sides are driven to rotate by the middle bevel gear so as to enable a lead screw to rotate and further drive the removable connecting plate to rise or fall. The tension-torsion testing machine and the testing method disclosed by the invention have the advantages that integration of the tension-torsion test can be realized, and more convenience can be brought for the test; all characteristic parameters and dynamic characteristic curves can be displayed in the measurement process, statistic analysis is carried out on measured data, and a measured result is outputted; and the economic and practical effects are achieved and the space can be saved.
Description
Technical field: [0001] The invention relates to the field of material mechanics testing, in particular to a tensile and torsion testing machine and a testing method suitable for measuring various characteristic parameters of material stretching and torsion. Background technique: [0002] With the development of modern industry, modern new materials emerge in an endless stream. In order to explore the specific parameters of new materials in various complex environments (high temperature, high pressure, vacuum, corrosion, etc.), it is necessary to conduct accurate tensile, compressive and torsion tests to obtain better results. Mechanical properties, process properties, structural strength, etc., so as to control product quality. At present, testing machines are widely used in various fields and departments such as machinery, construction, transportation, transportation, metallurgy, chemical industry, textile, aviation, aerospace, energy development, new materials, etc. The r...
