The verification method of a torsion testing machine is to clamp the standard tensile sample of the corresponding force value onto the testing machine according to the force value in the tested range of the torsion testing machine. The verification method of the torsion testing machine is described in detail by the editor below:
Firstly, let the torsion testing machine stretch the standard torsion force specimen at the specified speed according to the standard. When the standard tension specimen is in a tensile state, install an extensometer or attach a strain gauge on it, and let the torsion testing machine continue to stretch the standard tension specimen. The extensometer or strain gauge displays the elongation of the standard tension specimen. This method utilizes Hooke's law, The accuracy of the testing machine is determined by comparing the elongation of the standard tensile specimen to the force value and the dial force value of the testing machine
The verification method of the torsion testing machine greatly simplifies the verification process and brings great convenience and standardization to the daily verification of the original tensile state of the torsion testing machine. According to Hooke's law, the elongation is converted into a torsion value, and then compared with the same force value point on the dial of the tensile testing machine as the standard torsion force sample. The technical status and accuracy of the torsion testing machine are determined based on the difference in the comparison values
