What is an impact testing machine?
In the fields of industrial production and scientific research, the impact testing machine is an important testing equipment used to evaluate the performance of materials or products when subjected to impact force. With the advancement of science and technology, the application range of impact testing machines is becoming more and more extensive, from automobile manufacturing to aerospace, from building materials to electronic products, all of which are inseparable from its test data. This article will introduce in detail the definition, working principle, application fields of impact testing machines, as well as hot topics and hot content in the past 10 days.
1. Definition of impact testing machine
An impact testing machine is a device used to simulate and measure the reaction and performance of materials or products when subjected to sudden impact forces. It tests key indicators such as impact strength, toughness, and fracture performance of materials by applying high-energy impact force. Impact testing machines usually consist of impact devices, measurement systems and control systems, which can accurately record force, displacement, energy and other parameters during the impact process.
2. Working principle of impact testing machine
The working principle of the impact testing machine is based on the law of conservation of energy. During the test, the impact hammer falls freely from a certain height or is accelerated by a mechanical device to impact the sample. During the impact process, the deformation and fracture of the specimen will absorb part of the energy, and the remaining energy is recorded by the measurement system. By analyzing this data, the material's impact resistance can be evaluated.
| parameters | Description |
|---|---|
| impact energy | The energy released by the impact hammer when it hits the specimen, in Joules (J) |
| Impact speed | The speed of the impact hammer when it hits the specimen, in meters per second (m/s) |
| Sample size | Length, width and thickness of the specimen in millimeters (mm) |
| fracture energy | The energy absorbed when the sample breaks, in joules (J) |
3. Application fields of impact testing machine
Impact testing machines are widely used in many industries. The following are its main application areas:
