The machine can realize closed-loop control of parameters such as test force, sample deformation, and beam displacement, and can realize constant force, constant displacement, constant strain, constant velocity load cycle, constant velocity deformation cycle, and other tests. Users can use the PC expert system to independently set control modes such as constant stress, constant strain, and constant displacement, and switch between various control modes smoothly.

1. The design of the main body of the testing machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance, no pollution, low noise, and high efficiency.
2. The testing machine adopts the AC servo speed control system and motor with high-speed control precision and stable performance as the driving system;
3. The specially designed synchronous toothed belt deceleration system and ball screw pair drive the moving beam of the testing machine;
4. The control and data processing software based on database technology with Windows as the operating platform adopts virtual instrument technology to replace the traditional digital tube and oscilloscope, and realizes the screen of test force, test force peak value, beam displacement, sample deformation, and test curve. Display, all test operations can be completed on the computer screen by means of mouse input, with a good man-machine interface, easy to operate;
5. The dual-channel all-digital program-controlled amplifier installed in the PC realizes the real physical zero adjustments, gain adjustment and automatic shifting, zero adjustments and calibration of test force measurement, without any analog adjustment link, the height of the control circuit Integrated, completely cancel the potentiometer and other mechanical adjustment devices, simple structure, reliable performance.
