1. Using electronic servo and DDR torque motor drive technology, it has the advantages of high efficiency, long life, low noise and maintenance-free;

2. The testing machine adopts a "horizontal floor structure" with good dynamic stability, and the test bench is convenient, random, safe and reliable;

3. The parameters required for different tests—torque, frequency, rotation angle, etc., can be set and displayed on the computer screen, and the progress of the test can also be called and inquired at any time;

4. User operation interface: The test software can be operated under the Windows system, and the microcomputer system can complete test settings, working status control, data acquisition, and calculation processing. Simple and reliable human-computer interaction interface and data processing interface, complete different experimental requirements selected by users, display and print test results;

5. Open data structure: Both result parameters and process data allow users to call randomly, which is very convenient for scientific research and teaching;

6. Various protection measures: when the sample is damaged, the tooling is broken and the equipment fails, the test will be automatically stopped and alarmed. During the automatic control test, the testing machine has overload, over-angle, over-temperature, electronic limit protection, over-current, over-current Various electrical protections in the power link, software part overload, mechanical forced safety limit protection, etc.
