The electric stretch tester is a device used to test the tensile properties of materials. It evaluates a material's mechanical properties such as tensile strength, breaking strength, elongation, and modulus of elasticity by applying force or strain. It is a common tool for testing the mechanical properties of materials and is widely used in material science, engineering and quality control.
Electric stretch tester usually consists of the following main parts:
1. Loading system: The loading system is the part used to apply force or strain. Common loading systems include electric servo drives, electric motors, and screws.
2. Clamp system: The clamp system is used to fix the material sample to ensure that the material is subjected to uniform force during the stretching process. The fixture system usually consists of an upper fixture and a lower fixture, which can be adjusted according to different testing requirements.
3. Control system: The control system is used to set test parameters and collect data. It is usually operated by a computer or a control panel, which can monitor data such as load, strain and displacement in real time, and can display and record the data through graphs or images.
4. Data acquisition system: The data acquisition system is used to collect the data generated in the experiment. It can record parameters such as load, displacement, deformation and time, and then perform calculations and analysis based on these data.
The working principle of the electric stretch tester is to make the material generate stress during the stretching process by applying a constant load or strain, and then measure the mechanical properties of the material according to the relationship between the strain and the load of the material.
In practical applications, the electric stretch tester can be used to test the mechanical properties of different materials, such as metals, plastics, fibers and composite materials. By performing tensile tests on these materials, important indicators such as their quality, viability and service life can be assessed.
In conclusion, the electric stretch tester is a device used to test the mechanical properties of materials, which can evaluate the tensile properties of materials by applying force or strain, and plays an important role in the fields of material science and engineering.
