What is a fully automatic tensile testing machine?
In the fields of industrial production and materials research, the fully automatic tensile testing machine is an important testing equipment used to measure the mechanical properties of materials, such as tensile strength, yield strength, elongation, etc. With the advancement of science and technology, the application range of fully automatic tensile testing machines is getting wider and wider, becoming one of the core tools for material testing. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of fully automatic tensile testing machines.
1. Definition of fully automatic tensile testing machine
The fully automatic tensile testing machine is a device that automatically completes mechanical properties testing of materials such as tension, compression, and bending under computer control. It can accurately record load, displacement, deformation and other data during the test process, and generate detailed test reports. Compared with traditional manual or semi-automatic testing machines, fully automatic tensile testing machines have higher testing efficiency and accuracy.
2. Working principle
The working principle of the fully automatic tensile testing machine mainly includes the following steps:
1.Sample holder: Fix the material to be tested in the upper and lower clamps of the testing machine to ensure firm clamping to avoid slipping or falling off during the test.
2.load test: Tension is applied through a servo motor or hydraulic system to gradually stretch the material until it breaks.
3.Data collection: The sensor collects load, displacement, deformation and other data in real time and transmits it to the computer system.
4.data analysis: Computer software automatically calculates the mechanical property parameters of materials and generates test reports.
3. Application fields
Fully automatic tensile testing machines are widely used in the following fields:
| Industry | Application scenarios |
