Introduction:
This machine is mainly used for testing the tensile stress relaxation mechanical properties of metal materials (such as steel strands, PC steel bars and steel wires) at room temperature. The system adopts imported servo motor as the power source, and has the functions of force closed loop and displacement closed loop control. It can realize constant speed load control, load holding, constant speed displacement control, displacement maintenance, constant speed deformation control, deformation and maintenance, etc. The control precision is high. The reliability is good, and the product meets the relevant requirements of the tensile stress relaxation test of steel at room temperature in the GB/T 10120-1996 Metal Stress Relaxation Test Method and the ASTM E328-2008 Material and Structural Stress Relaxation Test Method. The system uses a microcomputer to realize electronic measurement, automatically collect and save test data, and automatically calculate and print reports.
Performance characteristics:
1, using high-precision amplifier and A / D converter, effective internal code ± 200000, the whole process is not divided, first-class accuracy, measurement range 2% -100% FS, digital real-time display load, load peak, loading speed;
2. Have the relationship between residual test force or relaxation rate and time.
3. The stress relaxation performance of the test piece for 1000 hours can be derived.
4, using PID closed-loop control strategy to achieve constant speed loading, with a loading rate of 100 ~ 5000N / S arbitrary setting function.
5. The stress relaxation properties (such as stress relaxation rate) of the test piece can be automatically obtained and a complete test report can be printed.
6. Load and displacement are digitally calibrated.
7. It has the function of storing test results and can review and traverse the test process.
8. Automatically adjust the coordinates: Enter the test state, the system automatically adjusts the coordinate size, and the complete curve is always displayed during the whole test.
9. Test parameters: The test parameters can be automatically stored, automatically recalled, or reset.
10. Data Picking: After the test is completed, the mouse can be used to pick up the data on the test curve.
