What is a metal impact testing machine?
The metal impact testing machine is a special equipment used to test the impact resistance of metal materials under dynamic loads. It is widely used in metallurgy, machinery manufacturing, aerospace, automotive industry and other fields to help engineers and researchers evaluate the toughness, brittleness and impact resistance of metal materials. This article will introduce in detail the definition, working principle, application fields and related data of metal impact testing machines.
1. Working principle of metal impact testing machine
The metal impact testing machine measures the energy absorbed by the material during the fracture process by simulating the sudden impact load that the material may be subjected to in actual use. The core principle is to apply impact force to the sample through a pendulum or falling weight, record the energy consumption when the sample breaks, and thereby calculate the impact toughness of the material.
| components | Function description |
|---|---|
| pendulum system | Provides impact energy and calculates the impact force through the swing height of the pendulum |
| Specimen fixture | Fix the specimen to ensure accurate impact position |
| energy measurement system | Record the energy consumption when the specimen breaks |
| data acquisition system | Store and analyze test data |
2. Application fields of metal impact testing machine
Metal impact testing machines have important applications in many industrial fields. The following are its main application scenarios:
| Application areas | Specific use |
|---|---|
