• Main frame:
The upper crossbeam and worktable are fixed with high-strength light bars to form a high rigidity frame structure; The high-precision ball screw without clearance is adopted to improve the transmission efficiency and displacement accuracy; The coaxiality of the testing machine is good (<8%). The upper, middle and lower beams are made of QT600-3 ductile iron with tensile strength of 60k (600MPa) and yield strength of 40k (400Mpa). The corrosion resistance and oxidation resistance of ductile iron are better than that of cast steel. Due to the microstructure of nodular graphite of ductile iron, it is better than cast steel in reducing vibration energy, so it is more conducive to reducing stress.

• Introduction to the CMT3200 servo control system of Sanshiheng:
CMT3200 controller system uses the servo measurement and control box and measurement and control software developed by our company to form the measurement and control system. The measurement unit uses high-precision load sensor, rotary photoelectric encoder and electronic extensometer, which can realize the three closed-loop control of load, displacement and deformation of the electronic universal testing machine, and can achieve smooth switching between the three control modes, and also can achieve low cycle fatigue test, It has the characteristics of high control accuracy, strong adaptability and good stability.
² Adopt Cortex_ The 32-bit high-speed ARM chip of M3 is used as the main control chip, which has high-speed operation speed and high-speed data processing ability, so as to achieve accurate closed-loop control of the testing machine;
² Support data acquisition of 6 channels and independent control of 6 channels;
The 6-channel channel supports online sensor identification, and the calibration table does not need to be modified to replace the sensor.
² Built-in expansion interface, combined with external acquisition module, can collect various types of sensor signals;
The load channel and extensometer channel can support up to 1.6KHz acquisition and control, the maximum effective sampling code can reach 500000, and the sampling frequency can be switched at any time;
The photoelectric encoder position acquisition module uses a special hardware module with a built-in 24-level filter to reshape and filter the collected pulse signal, avoiding the error count caused by the interference of the position pulse acquisition system, and more effectively ensuring the position measurement accuracy.
It has internal and external 2-way load sensor interfaces and can be connected to 2-way load sensors at the same time;
It supports 1 channel of large deformation channel, 2 channels of photoelectric encoder signals, and composite control algorithms such as sum, difference and average.
It supports three closed-loop control modes of load, displacement and deformation (including extensometer, large deformation and dial indicator), and can switch between the three control modes at will;
It adopts Ethernet communication interface, supports automatic online scheme, and does not need to set IP address.
