1. Definition of tensile impact testing machine
The tensile impact testing machine is an instrument used to test the mechanical properties of materials under tensile and impact loads. It measures key parameters such as tensile strength, impact toughness, and elongation at break of the material by simulating the dynamic loading conditions that the material may encounter in actual use.
2. Working principle
The working principle of the tensile impact testing machine mainly includes the following steps:
1.Specimen clamping: Fix the sample in the upper and lower clamps of the testing machine.
2.Load application: Apply tensile or impact load to the specimen through a hydraulic or motor drive system.
3.Data collection: The sensor records the deformation, load, fracture time and other data of the sample in real time.
4.Result analysis: The software system automatically generates test reports, including stress-strain curves, impact energy and other indicators.
3. Application fields
Tensile impact testing machines are widely used in the following industries:
| Industry | Application scenarios |
