The invention relates to the technical field of stress test experiments, in particular to a stress measurement method and a force measurement device for a prestressed workpiece, and the method comprises the following steps: 1, putting a workpiece to be measured into the force measurement device, and carrying out pre-force application processing and fixing; step 2, continuously heating the fixed workpiece to be detected at the temperature of 600-800 DEG C; 3, when the to-be-detected workpiece is rotated, stretching the two ends in the opposite directions at the same time; step 4, reading data by the force measuring device; 5, the qualified workpiece in the force measuring device is rotated for the second time; step 6, reading the data of the force measuring device at the moment; 7, the steps 1-6 are repeated, the tensile experiment can be synchronously carried out when the torsion experiment is carried out, the technical vacancy that only one-way measurement can be carried out in the prior art is filled, meanwhile, force measurement is carried out in an auxiliary mode through gear linkage and activation of material activity, and the accuracy of the force measurement result is improved.
Description
technical field [0001] The invention relates to the technical field of stress testing experiments, in particular to a force measuring method and force measuring device for prestressed workpieces. Background technique [0002] The mechanical properties of materials refer to the mechanical characteristics of materials when they are subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity). Among them, the tensile strength and torsional strength of materials have important practical measurement values, and the tensile strength and torsional strength are of decisive significance for actual building construction and mechanical equipment manufacturing. [0003] In the prior art, the stretching and torsion experiments for materials are all limited to simple single-item experiments, and it is impossible to perform two-way experiments of stretching and torsion at the same...
