1. Definition of double-arm tensile testing machine
The double-arm tensile testing machine is a mechanical testing equipment with a double-column structure. Two symmetrical columns support the cross beam to achieve tension, compression and other tests on the sample. Its core function is to measure key parameters such as tensile strength, yield strength, and elongation at break of materials.
2. Working principle of double-arm tensile testing machine
The double-arm tensile testing machine drives the beam to move through a motor, exerts tension or pressure on the sample, and records force and displacement data through high-precision sensors. Here is a brief description of its workflow:
| steps | Description |
|---|---|
| 1 | Install the specimen between the upper and lower clamps |
| 2 | Set test parameters (such as speed, maximum force value, etc.) |
| 3 | Start the test, the crossbeam moves to apply force |
| 4 | The sensor collects data in real time and transmits it to the computer |
| 5 | Software analyzes data and generates test reports |
