Abstract

The invention discloses a test and control method of a material testing machine. The test and control method comprises the following steps that: step one, field data acquisition is carried out: a load sensor, a displacement sensor and a deformation sensor are adopted to acquire the tensile force data of the material testing machine in material tensioning, the displacement quantity data of the rise of a crossbeam, and the deformation quantity data of a material to be tested respectively in real time; second step, data pre-processing and transmission are carried out; step three, data storage and wireless transmission are carried out; step 4, data remote processing and display are carried out; and step 5, a motor responds to a control command until a test is terminated; step six, test data are printed, and test work is completed. According to the test and control method of the material testing machine the invention, wireless communication technologies and sensor technologies are utilized, and therefore, the real-time automatic acquisition, analysis and processing of the test data and automatic control on an actuator can be realized, test precision can be ensured, and investment and maintenance cost can be greatly reduced.

Description

technical field [0001] The invention relates to a measurement and control method, in particular to a measurement and control method of a material testing machine. Background technique [0002] Material science is the foundation of industry and manufacturing, and all industrial manufacturing must be based on material science. The development of various new materials and new products is inseparable from the testing of material properties. In the development of materials science, in order to explore and study the mechanical properties of new metals, alloys, compounds, polymer materials and composite materials, it is necessary to use materials testing machines and other instruments in various complex environments (such as high temperature, low temperature, high pressure and corrosive media, etc.) for precise testing. Reasonable and reliable products can be designed and manufactured only after understanding the mechanical properties of materials, and the electronic universal ma...
