What is an impact testing machine?
In the fields of industrial production and materials research, impact testing machines are important testing equipment used to evaluate the performance of materials or products when subjected to sudden impact. This article will introduce in detail the definition, working principle, application fields and recent hot topics of impact testing machines.
1. Definition of impact testing machine
An impact testing machine is a device that simulates the impact that materials or products may experience in actual use. By applying controllable impact loads, key indicators such as impact resistance, toughness, and strength of materials are tested. This equipment is widely used in the automotive, aerospace, electronics, packaging and other industries.
2. Working principle of impact testing machine
Impact testing machines usually consist of impact heads, specimen fixtures, data acquisition systems and control systems. When working, the impact head hits the sample at a set speed and energy, and the sensor records the force, displacement, energy and other parameters during the impact process, and finally generates a test report.
3. Application fields of impact testing machine
The following are the main application areas of impact testing machines:
| Industry | Application scenarios |
|---|---|
| automobile manufacturing | Test the impact resistance of body materials, airbags, and bumpers |
