The microcomputer control electronic universal testing machine is a new generation of microcomputer controlled electronic universal testing machine specially designed for colleges and universities and scientific research institutes. The computer system through the full digital controller, through the speed control system to control the servo motor rotation, through the deceleration system deceleration through the precision ball screw pair to drive the moving beam up and down, to complete the sample tensile, creep, hardness, compression, bending, shear and other mechanical properties of the test, in addition to a wide variety of test attachments, in the metal, non-metal, composite materials and products of mechanical properties test, has a very broad application prospects. The machine is widely used in building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, textiles, home appliances and other industries of material inspection and analysis, is a scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments of reliable testing equipment.
host
The main machine adopts a high-rigidity portal frame structure, with high strength and small deformation
Imported high-precision ball screws are used to drive efficiently and smoothly
The transmission part is driven by arc tooth synchronous belt, and there is no gap in both directions during the transmission process
AC servo motor and drive system are used to ensure stable transmission and stable torque, with overcurrent, overVoltage, overload and other protection devices, and the speed regulation ratio can be larger than 1:100000
The clamp is specially designed, the clamping is firm, the operation is convenient, and there is no jaw slippage
The special process ensures the coaxiality of the testing machine, and eliminates the influence of irregular specimens on the sensor
Control system
The STC300 all-digital closed-loop measurement and control system has many advanced features and technological innovations, which are mainly reflected in:

1. Four closed-loop controls of test force, sample deformation, beam displacement and test process are realized
2. The data acquisition system consists of 4 high-precision 24-bit A/D conversion channels. The highest resolution is 1/300000, and the whole process is not divided
3. Select BB, AD, Xilinx and other original integrated devices, fully digital design
4. In line with PCI bus standards, microcomputer automatic identification and installation, so as to achieve "plug and test"
5. The electronic measurement system does not have analog components such as potentiometers, which ensures interchangeability and is convenient for maintenance and replacement
