Guangzhou Huangpu Shipyard: 300kN microcomputer control electronic universal testing machine project
The ETM305D 300kN microcomputer controlled electronic universal testing machine project of Wanji Company purchased by Guangzhou Huangpu Shipyard is mainly used to test metal materials in the tensile test of metal materials at high temperature and normal temperature,It is equipped with the proprietary hydraulic jig of Wanji Company,Used to meet the new GB/T 228 standard,Tensile tests are carried out on metal materials,The upper and lower yield strength, the non-proportional elongation strength, the total elongation strength, the residual elongation strength, the tensile strength and the elongation rate were obtained by hysteresis loop method。
Main features:
1: The use of high-speed DSP platform, its high integration, powerful control, data processing capabilities, high reliability, is the use of other processors of the testing machine can not be matched。
2: Adopt the all-digital, three-closed loop (force, deformation, displacement) control system based on neuron adaptive PID algorithm to realize the all-digital three-closed loop control of force, deformation, displacement, which can automatically switch between the control rings and realize the smooth transition without impact when switching between different modes。
3: Test force, deformation, displacement and other speed control and maintenance。
4: Closed-loop control parameters online identification。
5: High precision 24Bit data acquisition system, high resolution, can be expanded to 8 AD acquisition。
6: USB1.1 Communication, the communication rate is 12Mb/s, using full speed mode, batch transmission mode。
7: The system board adopts a unique anti-interference wiring method of 4-layer PCB, which has strong anti-interference ability。
8: In addition to the power interface, other interfaces are standard USB interface, plug and play interface This interface can be hot-swappable, that is, with plug and play function。Interface features can be set online by software。The layout of each interface is neat and reasonable, and easy to plug and remove。
Meet the criteria:
GB/T16491 "Electronic Universal Testing Machine"
GB/T 228 "Tensile test method for Metal materials at room temperature"
Sweep for immediate attention
