Product Introduction:

1. Host structure:

1.1. The stretching mechanism of the WDWS series microcomputer controlled balance bar tensile testing machine includes two pairs of guide rails and their driving components, two sets of fixtures and their driving components. Among them, the two guide rails in each pair are parallel to each other, and the independent servo motor reducer sensor can be loaded separately and simultaneously. The test piece is fixed on the bracket, and the circular arc groove is matched with different test pieces to force clamping and prevent axial movement. The software sets the loading speed and deformation value at both ends separately. Click start, and independently synchronize the stretching, (pulling one by one)

1.2. After reaching deformation, stop the machine (the software is set with process judgment, and during the experiment, if there is a fracture, the machine will automatically stop. When the machine stops, the other path will continue to work without affecting each other).

1.3. Adjust the tooling to conduct shaft end tension (20000N) experiments,

2. Electrical system:

(1) Adopting AC servo drivers and AC servo motors, the performance is stable and reliable, with protection devices for overcurrent, overvoltage, overspeed, overload, etc. The speed ratio can reach 1:1000.

(2) It has protection functions such as overload, overcurrent, overvoltage, displacement upper and lower limits, and emergency stop.

(3) The electrical control circuit is in accordance with the electrical standards of the testing machine, with strong anti-interference ability, ensuring the stability of the controller and the accuracy of experimental data.

3. Control system:

The fully digital closed-loop measurement and control system independently developed by our company has many characteristics and technologies, mainly reflected in:

1. Four closed-loop controls have been implemented for testing force, specimen deformation, displacement, and testing process;

2. The data acquisition system consists of 4 high 24 bit A/D conversion channels. The resolution reaches 1/300000, and the entire process is not divided into different levels;

3. Using original integrated components such as BB, AD, Xilinx, etc., with fully digital design;

4. Compliant with PCI bus standard, automatically recognized and installed by microcomputer, achieving "plug and test";

5. The electronic measurement system does not have analog components such as potentiometers, ensuring interchangeability and facilitating maintenance and replacement
