What is a semi-automatic impact testing machine?
In the fields of industrial production and materials research, the impact testing machine is an important testing equipment used to evaluate the impact resistance of materials under dynamic loading. In recent years, with the advancement of technology, semi-automatic impact testing machines have gradually become popular in the market due to their high efficiency and accuracy. This article will introduce in detail the definition, working principle, application fields and recent hot topics of semi-automatic impact testing machines.
1. Definition of semi-automatic impact testing machine
Semi-automatic impact testing machine is an impact testing equipment between manual and fully automatic. It improves testing efficiency through partially automated operations (such as data collection and result analysis) while retaining the flexibility of manual intervention. It is widely used in impact performance testing of metals, plastics, composite materials and other materials.
2. Working principle
The semi-automatic impact testing machine applies impact force to the sample through a pendulum or falling weight, and records the energy absorption value when the sample breaks to evaluate the toughness or brittleness of the material. Its core components include:
| components | Function |
|---|---|
| pendulum system | Provides impact energy, adjustable height and angle |
| Specimen fixture | Fix the specimen to ensure test stability |
| Data acquisition module | Automatically record impact force, displacement and other parameters |
| control system | Enable semi-automatic operation (e.g. pendulum release) |
3. Application fields
Semi-automatic impact testing machines have important applications in the following industries:
| Industry | Specific use |
|---|---|
| automobile manufacturing | Test the crash resistance of body materials |
| Aerospace | Evaluate the dynamic strength of composite materials |
| Building materials | Testing the impact resistance of glass and concrete |
