1. Definition of computer-based material testing machine
A computerized material testing machine is a precision instrument controlled by a computer, used to test the mechanical properties of various materials. It can conduct various mechanical tests such as tension, compression, bending, and shearing on metals, plastics, rubber, composite materials, etc., and automatically record and analyze test data.
| Main components | Function description |
|---|---|
| Load system | Apply force to specimen |
| Measurement system | Accurately measure force and deformation |
| control system | Computer controlled test process |
| data processing system | Collect, store and analyze data |
2. Working principle
Computer-based material testing machines generate mechanical force through servo motors or hydraulic systems, which act on test samples. At the same time, high-precision sensors measure the deformation of the sample during the stress process, and all data are collected and processed in real time by the computer.
| Test steps | Detailed description |
|---|---|
| 1. Sample preparation | Prepare test samples according to standards |
| 2. Parameter settings | Set test speed, termination conditions, etc. |
| 3. Start testing | Automatically apply force and record data |
| 4. Data analysis | Generate results such as stress-strain curves |
3. Main application areas
Computer-based material testing machines are widely used in all walks of life. The following are its main application scenarios:
| Industry | Application examples |
|---|---|
| automobile manufacturing | Test the strength of auto parts |
