Abstract

Stress relaxation performance is an important performance indicator for evaluating elastic materials or components. The accuracy of relaxation testing machines directly determines the accuracy of the detection results of relaxation tests, which affects the effectiveness and reliability of the detection results. For a long time, the calibration work of the relaxation testing machine has not been carried out, and the testing and testing institutions cannot grasp the accuracy of the relaxation testing machine equipment itself. To achieve the calibration of the relaxation test force value system, the requirements for calibration parameters were clarified, and a calibration test for the relative error of force value indication was designed, and its uncertainty was evaluated.
