With the further improvement of the national scientific and technological strength, breakthroughs have been made in such fields as measurement, control, computer application and digital digitization. At this time, it is very important how to apply the material reasonably, safely and efficiently and test its mechanical properties Based on a variety of new technologies, new programs are widely used in the field of testing machine, universal testing machine industry has also made considerable development.
The so-called universal testing machine, is a set of tensile, bending, compression, cutting and other functions in one of the material testing machine, mainly used for mechanical properties of metals, non-metallic materials testing. As metallurgy, construction, light industry, aviation, aerospace, materials , Universities, research institutes, engineering quality supervision station and other departments ideal testing equipment, in all walks of life have played a role that can not be ignored.Of course, with the continuous upgrading of production and application needs, the urgent need for the relevant software technology Performance optimization, thus promoting the scientific and orderly development of industrial development.
Universal testing machine computer data acquisition system is mainly used for tensile, compression and bending of materials such as mechanical properties determination.In order to further enhance the universal testing machine computer data acquisition system in the detection of the accuracy and efficiency, to reduce due to various factors Error, recently, the National Strength Hardness Gravimetric Measurement Technology Committee released a "universal testing machine computer data acquisition system assessment," draft, and facing the country's measurement agencies, research institutes and other relevant units for comments.
According to the introduction, "Universal Testing Machine Computer Data Acquisition System" norms according to JJF 1071-2010 "National Metrology Preparation of rules for the preparation of calibration rules "for the preparation of rules applicable to universal testing machine quasi-static test computer data acquisition system (hereinafter referred to as computer data acquisition system) data accuracy and consistency assessment.
Science, compliance, and applicable methods can better promote the development of the industry standard.In this regard, this specification in the process of making full account of the GB / T 228 "tensile metal materials," GB / T 16491-2008 "electronic universal Testing machine ", JJG 139-2014" Rally, pressure and universal testing machine test procedures ", JJG 475-2008" electronic universal testing machine test procedures "and other standards of the terms, symbols and definitions and related technical requirements, technical indicators and Test methods. In addition, also cited GB / T 228 metal material drawing method, GB / T 12160-2002 uniaxial test with extensometer calibration, GB / T 16491-2008 electronic universal testing machine, JJG 475-2008 Electronics Universal testing machine test procedures and other literature.
Universal testing machine industry development not only rely on the promotion of national policies, but also inseparable from the test of the core competitiveness of products. Only in this way, universal testing machine to achieve healthy development and consolidate the position within the industry. "Universal Test Machine Computer Data Acquisition System Evaluation "Release Draft, right instrument The measurement performance, technical requirements and other provisions will help the instrument in more areas more standardized use.
