Verification method and device of computer data acquisition system for material testing machine

Abstract

The invention relates to a method and a device, in particular to a method and a device for verifying a computer data acquisition system for a material testing machine. According to the technical scheme provided by the present invention, the verification method of the computer data acquisition system for the material testing machine includes a computer data acquisition system; the required sample test reference signal and computer data are loaded at the input end of the computer data acquisition system. The acquisition system uses the loaded sample test reference signal to directly evaluate and verify the collected sample test signal, and output the corresponding evaluation and verification results. The invention has the advantages of simple structure, wide application range and convenient operation, can effectively evaluate the computer data acquisition system, and improves the reliability of the evaluation result and the evaluation efficiency.

Description

technical field [0001] The invention relates to a method and a device, in particular to a method and a device for verifying a computer data acquisition system for a material testing machine. Background technique [0002] Material testing machine (hereinafter referred to as testing machine) refers to precision testing equipment for measuring the mechanical properties of metal materials, non-metal materials, mechanical parts, engineering structures, etc. under various conditions and environments. It is mostly used for metal and non-metal (including composite materials) ) Static performance testing and analysis of tensile, compression, bending, shearing, splitting, bending resistance, peeling, tearing and other items. In the process of researching and exploring new materials, new processes, new technologies and new structures, The testing machine is an indispensable and important testing equipment. Among them, the tensile test is the most commonly used working state of the tes...

Problems solved by technology

Due to the uncertainty of the sample (such as the uniformity of the material, processing errors, etc.), the elastic modulus and tensile strength of each sample in the "same sample" also have large differences, and there may be errors in the direction of the testing machine The opposite situation makes the verification results less reliable
