WDW series electronic universal testing machine

1、 Product Introduction:

WDWThe series of microcomputer controlled electronic universal testing machines is a new generation of microcomputer controlled electronic universal testing machines designed specifically for higher education institutions and research institutes. The design of the main unit and auxiliary equipment of the testing machine draws on the technology of Shimadzu in Japan, with beautiful appearance, easy operation, stable and reliable performance. The computer system controls the servo motor to rotate through a controller and a speed regulation system. After being decelerated by a reduction system, it drives the moving crossbeam to rise and fall through a precision screw pair, completing various mechanical performance tests such as tension, compression, bending, and shearing of the sample. It is pollution-free, low-noise, and highly efficient, with a very wide speed regulation range and crossbeam movement distance. In addition, it is equipped with a variety of test attachments, which have a very broad application prospect in the mechanical performance testing of metal, non-metal, composite materials, and products. This machine is widely used for material inspection and analysis in industries such as fur testing, building materials, aerospace, machinery manufacturing, wires and cables, rubber and plastics, textiles, and home appliances. It is an ideal testing equipment for scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commercial inspection and arbitration departments.

The machine adopts a servo speed control system with high precision and stable performance, as well as a servo motor as the driving system, and a controller as the core of the control systemWINDOWSFor the control and data processing software of the operation interface, the screen display of test force, peak test force, beam displacement, test deformation, and test curve can be achieved. All test operations can be automatically completed on the computer through the mouse. Good humanized design makes the experimental operation more convenient. Provide users with multiple standards for experimentation and data processing, and have good scalability.

2.1Computer control systems have the advantages of high integration, stable performance, and easy adjustment. Real time collection of experimental data can be achieved, and real-time dynamic display of experimental characteristic curves can be realized. Experimental data files can be saved in commonly used databases or large databases, which facilitates customer resource sharing and network management, as well as user reanalysis. This software can process raw data of experimental force, displacement, time, deformation, and the curves derived from them.

2.2protection function:This machine has two types of limit protection: software and mechanical,The proportion of automatic shutdown beyond the maximum load can be dynamically set;It has multiple protection functions such as overcurrent, overvoltage, overload, etc.

2.3For load and deformation channels, automatic labeling can be achieved, which is intuitive and convenient.

2.4Batch testing can achieve hierarchical display of curves and automatic curve tracking.

2.5This software can achieve user-defined speed settings and computer adjustment of speed. It can also achieve high-precision speed calibration, adjust speed gear and coding at any time.

2.6Monitoring the experimental process: Real time display of various parameters such as test force, deformation, displacement, and curve during the experimental process can be achieved.

2.7Result reproduction function: After the experimental operation is completed and saved, it can be opened and reanalyzed at any time according to the user's needs.

2.8Curve point by point traversal function: You can click on the force and deformation values on the curve with the mouse to obtain various parameters for each point.

2.9Result comparison function: Multiple experimental curves can be observed simultaneously, and the comparison of the characteristics of the sample to be analyzed can be achieved through the superposition and local magnification of multiple curves.
