Electro-hydraulic servo torsion fatigue testing machine

Functional purpose:

It is mainly used for torsion test of various materials such as metal and non-metal. It can realize torque and torsion angle control. With the addition of corresponding accessories, it can also conduct torsion test of parts and components. Under the computer control mode, equipped with a small angle measuring device can accurately obtain test data such as torsional elastic modulus (shear modulus G) and non-proportional stress (TP).

According to the standard


1. Using hydraulic rotary 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. 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, work 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, broken or equipment failure, 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, and over-voltage. Various electrical protections such as power links, software part overload, mechanical mandatory safety limit protection, etc.
