What is a cantilever impact testing machine?
The cantilever impact testing machine is a special equipment used to test the impact resistance of materials. It is widely used in the field of quality inspection of plastics, rubber, composite materials, metals and other materials. Evaluate the toughness, brittleness and impact resistance of materials by simulating their behavior when subjected to instantaneous impact forces. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the principle, application and market dynamics of the cantilever impact testing machine.
1. Working principle of cantilever impact testing machine
The working principle of the cantilever impact testing machine is based on the pendulum impact method. During the test, the pendulum falls freely from a certain height and impacts the sample fixed on the fixture. By measuring the energy difference before and after the impact of the pendulum, the impact strength of the sample is calculated. The specific data are as follows:
| parameters | Description |
|---|---|
| impact energy | Usually 1J~50J, can be adjusted according to material characteristics |
| pendulum angle | The initial angle is generally 150°, and the remaining angle after impact is used to calculate energy loss. |
| Sample size | The standard sample is 80mm×10mm×4mm, which can also be customized |
2. Application fields of cantilever impact testing machine
Cantilever impact testing machines play an important role in many industries. The following are its main application areas and typical cases:
| Industry | Application cases |
|---|---|
| Plastic products | Test the impact resistance of PVC, ABS and other materials |
