WDW-02 Microcomputer controlled electronic universal testing machine

1.Product Overview:

This series of testing machines is designed and produced by our company on the basis of absorbing internationally leading testing machine technology. This machine is widely used in industries such as building materials, aerospace, mechanical manufacturing, wires and cables, rubber and plastics, textiles, home appliances, etc. to test and analyze the mechanical performance indicators of various metal, non-metal, and composite materials. It is an ideal testing equipment for scientific research institutions, vocational colleges, industrial and mining enterprises, technical supervision, quality inspection and other departments.

This series of testing machines achieves automatic control of the testing process and data collection and analysis through computers, achieving full digitalization and automation of the data collection, analysis and control process. The control and data processing software using WINDOWS as the operating interface has achieved computer display of test force, peak test force, beam displacement, test deformation, and test curve. The good humanized design makes the test operation more convenient. This machine can achieve three closed-loop control modes: experimental force, deformation, and displacement, and can smoothly switch between control modes such as constant stress, constant strain, and constant displacement. This machine fully meets the corresponding national standard requirements, and can be tested and processed according to GB, ISO, JIS, ASTM, DIN, and various user provided standards, with good scalability.

2.Product structure and function: 

1.This series of machines adopts an AC servo motor and speed control system to drive the precision ball screw pair to move up and down, thereby achieving a wide range of stepless adjustment of the test speed, ensuring high accuracy, low noise, and high stability during the test process. 

2. The experimental control system has the advantages of high integration, stable performance, and easy adjustment. Experimental data can be collected in real-time, and experimental characteristic curves can be dynamically displayed in real-time. Experimental data files can be saved in the form of commonly used databases in Access, facilitating customer resource sharing and network management, as well as user reanalysis. For various user-defined Word 2000 reports, this software can easily access them, solving the problem of different users or the same user having different needs for experimental reports at different times. This software can process raw data of experimental force, displacement, time, deformation, and the resulting curves.

3. Protection function: This machine has two limit protection methods: software and mechanical, and the proportion of automatic shutdown exceeding the maximum load can be dynamically set; It has multiple protection functions such as overcurrent, overvoltage, overload, etc. 

4. Automatic labeling can be achieved for load and deformation channels, which is intuitive and convenient. 

5. Batch experiments can achieve hierarchical display of curves and automatic curve following.

6. This software can achieve user-defined speed settings and computer adjustment of speed. It can also achieve high-precision speed calibration and adjust the speed gear and encoding at any time. 

7. Monitoring the testing process: Real time display of various parameters such as testing force, deformation, displacement, and curve during the testing process can be achieved. 

8. Software permission grading management function: In order to improve the security of software and data, the software can achieve permission grading management function by setting different password protection.

9. Result reproduction function: After the experimental operation is completed and saved, it can be opened and reanalyzed according to the user's needs at any time in the future. 

10. According to user needs, load deformation, load time, load displacement, displacement time, deformation time and other curves can be selected for testing, data display, storage, analysis, and printing. 

12. Force interface: The force channel interface and testing software can be equipped with various sensors according to user needs, and can be calibrated, modified parameters, and tested normally.

13. Deformation interface: The deformation channel interface and testing software can be equipped with various types of extensometers according to user needs, and can be calibrated, modified parameters, and normal tests. 

14. The software operation interface is shown in the figure (different test requirements require slightly different software)
