Tension-torsion testing machine and testing method thereof

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
