The high-speed rail test machine adopts hydraulic loading, a cylinder-mounted main structure, and a pressure sensor measure the force. After amplification, the test force, peak value, and loading rate are digitally displayed. Adding accessories can expand the test scope. This test machine is mainly used for tensile, compression, bending and shear tests of non-metals such as metal box plastic, concrete, cement, etc. Let’s learn about the characteristics of the high-speed rail test machine.
The high-speed rail test machine is a cylinder-mounted main machine structure, which is mainly used for mechanical properties tests such as tensile, compression, bending and shearing of metals and non-metals. It can be widely used in machinery, building materials, metallurgy, scientific research units, colleges and universities, quality testing centers and commodity inspection departments.
Functional features of high-speed rail test machine:
1. Display method: The data and curves are displayed dynamically with the test process;
2. Automatic shutdown: After the sample is broken, the moving beam will automatically stop;
3. Automatic speed change: The speed of moving beams during the test can be automatically changed according to the preset procedure or can be changed manually;
4. Automatic calibration: The system can automatically realize calibration of display accuracy;
5. Automatic saving: the test is over, the test data and curves are automatically saved;
6. Manual shift: Automatically switch to the appropriate range according to the load size to ensure the accuracy of the measurement data;
7. Condition storage: Test control data and sample conditions can be made into modules, which facilitates batch testing;
8. Process implementation: The test process, measurement, display and analysis are all completed by the microcomputer;
9. Batch test: For samples with the same parameters, they can be completed in sequence after setting them once;
10. Test software: Chinese WINDOWS interface, menu prompts, mouse operation;
11. Curve traversal: After the test is completed, the curve can be reanalysed, and the test data corresponding to any point on the curve can be found with the mouse.
