What is an 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 loads. This article will introduce in detail the definition, working principle, application fields of impact testing machines, and related content in recent hot topics on the Internet.
1. Definition of impact testing machine
An impact testing machine is a device that tests the impact resistance of materials or products by applying an instantaneous impact load. It is widely used in metals, plastics, composites and other industries to help engineers and researchers understand how materials perform under extreme conditions.
2. Working principle of impact testing machine
The working principle of impact testing machines is usually based on free fall or pendulum impact. The following is its core workflow:
| steps | Description |
|---|---|
| 1 | The specimen is fixed on the testing machine |
| 2 | The impact device (such as a pendulum or falling weight) is raised to a predetermined height |
| 3 | Release the impact device and let it fall freely to impact the specimen. |
| 4 | Record the energy required to break or deform the specimen |
3. Application fields of impact testing machine
Impact testing machines play a key role in several industries, the following are their main application areas:
| Industry | Application scenarios |
