1. The electronic universal testing machine is a new generation of material testing equipment jointly developed by our company and well-known universities at home and abroad. It is mainly used to test the tensile, compression, bending, shearing, peeling, tearing and other mechanical properties of various metals, non-metals and composite materials. The system adopts microcomputer closed-loop control, has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in the measurement and control of load and displacement.

2. The design of the main machine of the testing machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance, no pollution, low noise and high efficiency. The design of the auxiliary equipment is matched with the main machine, the structure is wedge-shaped translation type, manual rotation clamping, and the sample is not subject to additional force. The clamping is convenient, reliable, and does not slip.

3. This series of testing machines uses a digital AC servo speed control system with high speed regulation accuracy and stable performance and a motor as the drive system; a specially designed synchronous toothed belt deceleration system and a ball screw pair drive the moving beam of the testing machine; The control and data processing software based on database technology using Windows as the operating platform adopts virtual instrument technology to realize the screen display of test force, test force peak value, beam displacement, sample deformation and test curve. All test operations can be performed in The computer screen is completed by mouse input. It has a good man-machine interface and is easy to operate; the comprehensive application of the above-mentioned technologies ensures that the machine can achieve closed-loop control of parameters such as test force, sample deformation and beam displacement. Realize constant force, constant displacement, constant strain, constant velocity load cycle, constant velocity deformation cycle and other tests.
