Calculation method of maximum force value of material testing machine

Material testing machineIt is an instrument used to conduct performance testing of materials such as tensile, compression, bending, etc. Depending on the different properties of the materials measured, customers may have noticed when purchasing the test machine that the test machine standards indicate the strength, testing force and other requirements of the material. The following is the calculation of the test machine force value explained to you by our company.

Material testing machineThe calculation of force value is based on the force value of the test machine's inspection interval, such as the tensile performance of the material, and the standard tensile sample of the response force value is clamped on the test machine, and theGB/T228-2002The standardized speed allows the tensile tester to stretch the standardized tensile tester. When the standardized tensile tester is in a tensile form, an extensometer or a strain gauge is installed on it, so that the tensile tester can continuously stretch the standardized tensile tester. The extensometer or strain gauge displays the elongation amount of the standardized tensile tester, converts the elongation amount into the tensile value, and then compares it with the same force value point as the standardized tensile tester dial on the tensile tester, and determines the skill shape and accuracy of the tester based on the difference in the comparison value.

This method uses Hooke's law to compare the elongation amount of the standard tensile test sample into force value and the force value displayed on the display screen of the test machine to determineTesting machineaccuracy.
