b,WindowsXP all Chinese interface, man-machine dialogue mode. The computer screen displays the test torque, torsion angle, various test curves (torque-time curve, torque-angle curve, angle-time curve, etc.) testing machine working status, etc.

c,The size of the curve coordinates can be adjusted according to the actual test data.

d,Output and print various test report formats (the report format can be output in Excel or Word format).

e,Comply with the relevant data processing requirements of JB/T9370-2007 "Technical Conditions for Torsion Testing Machines" and GB10128-2007 "Metallic Materials Room Temperature Torsion Test Methods".

f,The torque, maximum torque, and torsional strength of the test piece can be tested. Torque and torsion angle are automatically tracked and measured, and the test curve, torque value, torsion angle, and torsion speed are displayed. After the test, the test data is processed automatically, and the performance parameters such as the torque and torsion strength of the material can be automatically obtained; the report format can be freely prepared according to the user's requirements and the test report can be output and printed.

g,The test process can be simulated and reproduced.

i,The test data adopts database management mode, which is convenient for query and maintenance.

j,The operation of the software system can realize three-level user management, which is safe, convenient and fast

8.Different test plans can be established according to the requirements, and batch test can be carried out. The data is collected in real time during the test, the curve is drawn in real time, and the large database is used for data storage, which facilitates user resource sharing and reanalysis. After the test is completed, the data is automatically processed and saved. The test results can be viewed at any time and the test report can be printed. The test report format can be changed according to the different requirements of the user. The test machine's processing of the test data is in full compliance with the standards of the spring test machine.

9.Test method:
There are two kinds of test methods: manual test and program control test. The details are as follows:
a) A manual test can select a test speed, and then select the test stop condition. The test stop conditions include: the angle is reached, the twist angle is reached, and the torque is achieved in three ways.
b) During the program control test, the speed conversion can be realized. No manual intervention is required during the test, and the test machine automatically runs according to the prepared test conditions.

10.Material performance data is automatically processed based on the measured material curve. For the curve with obvious yield, the upper and lower torsional yield strength can be automatically determined; for the torque-torsion curve, the shear modulus can be automatically selected. For materials without obvious yielding, automatically choose to calculate the specified non-proportional torsional strength;

11.Set the test speed by yourself and stop automatically after the test is completed.

12.With overload automatic stop function.

13.The manual micro-feeding device can be configured to realize the micro-feeding under various load conditions, which is convenient for calibration and displacement fine adjustment.
 

1. The test results are automatically stored, and the test report is printed as needed. The report format can be changed according to user requirements.

 

1. Software Calibration Section

a) Force value calibration: The method of three-point calibration is used to make the test force value more accurate and higher precision.
b) Electronic torsion meter calibration: The calibration method of the electronic torsion meter is the same as the calibration method of the force value, which ensures the accuracy of the torsion angle.
