3XJ8108CMicrocomputer controlled cross flow fan tensile testing machineAdopting a high-precision and stable digital AC servo speed control system and motor as the driving system; Specially designed synchronous belt reduction system and ball screw pair drive the movement of the testing machine's moving crossbeam; The control and data processing software based on database technology using Windows as the operating platform adopts virtual instrument technology instead of traditional digital tubes and oscilloscopes, realizing the screen display of test force, test force peak value, beam displacement, test deformation, and test curve. All test operations can be completed on the computer screen by mouse input, with a good human-machine interface and convenient operation; The dual channel fully digital programmable amplifier inserted into the PC realizes true physical zeroing, gain adjustment, and automatic shifting, zeroing, and calibration of test force measurement, without any analog adjustment links. The control circuit is highly integrated, eliminating mechanical adjustment devices such as potentiometers, with a simple structure and reliable performance. The comprehensive application of the above technologies ensures that the machine can achieve closed-loop control of parameters such as test force, sample deformation, and beam displacement, and can perform tests such as constant force, constant displacement, constant strain, constant velocity load cycle, and constant velocity deformation cycle. Users can use the PC expert system to independently set control modes such as constant stress, constant strain, and constant displacement, and smoothly switch between various control modes.

This provides convenience for post-processing such as reanalysis of experimental data, database management, and network transmission.

5. Due to the automatic control of the testing process and the information processing of the test results, the testing machine enables operators to conveniently and autonomously set the test program control steps. During the tensile test, the tester can clearly observe the entire testing process of low carbon steel, cast iron, etc. By repeatedly loading on different curve segments, the force displacement (deformation) curve can be used to intuitively verify Hooke's law and observe the phenomenon of cold work hardening. For materials without obvious physical yielding phenomenon, hysteresis loop method or stepwise approximation method can be used to determine the specified non proportional tensile strength. During the compression process, it is convenient to observe the yielding and strengthening phenomena of low carbon steel, as well as the compression failure process and fracture shape of cast iron. It can also detect the n-value and r-value of mechanical materials.
