What is a metal tensile testing machine?
The metal tensile testing machine is a professional equipment used to test the mechanical properties of metal materials. It is widely used in industrial manufacturing, scientific research experiments and quality inspection fields. It measures key parameters such as tensile strength, yield strength, and elongation of materials by applying tensile force, providing a scientific basis for material performance evaluation. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the principles, applications and market trends of metal tensile testing machines.
1. Working principle of metal tensile testing machine
The metal tensile testing machine applies axial tension to the sample through a hydraulic or motor drive system, records the force value and deformation at the same time, and generates a stress-strain curve. Here are its core components:
| components | Function description |
|---|---|
| Loading frame | Provide rigid support to ensure uniform force |
| sensor | Measure force and deformation in real time |
| control system | Adjust loading rate and data collection |
| fixture | Fix the specimen to prevent slipping |
2. Recent popular application fields
According to the analysis of the entire network data in the past 10 days, the attention of metal tensile testing machines in the following fields has increased significantly:
| field | Popular events | Related technical requirements |
|---|---|---|
| New energy vehicles | Demand for battery case material testing surges | High-precision strain measurement |
| Aerospace | Breakthrough in research and development of new titanium alloy | High temperature environment test |
| 3D printing | Metal print performance verification | Micro specimen fixture design |
3. Technology development trends
By analyzing recent industry trends and technical forum discussions, metal tensile testing machines show the following development trends:
1.Intelligent upgrade: Internet of Things technology enables remote monitoring and data analysis, and a new model of a certain brand supports AI to predict material failure points.
2.Multifunctional integration: Tensile-fatigue composite testing machines have become a hot spot for scientific research institutions to purchase, and can complete multiple tests simultaneously.
3.Green energy saving: The newly developed electro-hydraulic servo system reduces energy consumption by 40% and has been selected into the energy-saving product catalogs of many local governments.
4. Comparison of typical technical parameters
The following is a comparison of the core parameters of the top three models sold on recent e-commerce platforms:
| Model | Maximum load(kN) | Accuracy level | Sampling frequency (Hz) | price range |
|---|---|---|---|---|
| UTM-5000 | 50 | Level 0.5 | 1000 | 80,000-120,000 |
| MTE-100 | 100 | Level 1 | 500 | 50,000-80,000 |
| HT-300A | 300 | Level 0.5 | 2000 | 150,000-200,000 |
5. Purchase suggestions
Based on recent user consultation hot spots, it is recommended to select equipment from the following dimensions:
1.Testing requirements: Level 1 accuracy is optional for ordinary carbon steel testing, and level 0.5 or above is recommended for aviation materials.
2.Expansion capabilities: Pay attention to whether subsequent installation of compression, bending and other test modules is supported.
3.After-sales service: Recently, third-party repair disputes have occurred in many places. It is recommended to choose a brand with a complete original service network.
4.Software compatibility: The newly released GB/T 228.1-2021 standard puts forward new requirements for data processing, and it is necessary to confirm that the software can be upgraded.
