MODEL WDW-200D 

COMPUTER CONTROLLED ELECTRONIC UNIVERSAL TESTING MACHINE

 

Application

 

    WDW-200D is widely used in tensile, compression, bending and shear tests of metal and nonmetal materials. With a variety of accessories, it can also be used to test the mechanical properties of profiles and components. It also has a very wide application prospect in the field of rope, belt, wire, rubber, plastic and other materials with large sample deformation and fast test speed. It is suitable for quality supervision, teaching and scientific research, aerospace, iron and steel metallurgy, automobile, construction materials and other experimental fields.

 

Standards

 

    It meets the requirements of GB/T 228.1-2010 <<Tensile test method for metallic materials at room temperature>> and GB/T 7314-2005 <<Compression test method for metals>>, as well as ISO 7500-1, ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO6892, etc. It conforms to the requirement of data processing of GB, ISO, ASTM, DIN and other standards.

 

Main machine structure

 

    The main machine adopts double space portal structure, with upper space stretching, lower space compressing and bending. The crossbeam is stepless lifting. The transmission part adopts arc synchronous toothed belt, and the lead screw pair drives, with stable transmission and low noise. The specially designed gear belt speed reduction system and precision ball screw pair drive the moving beam of the testing machine to move, realizing no gap transmission.

 

Accessories

 

    Standard configuration: a set of wedge tensile testing attachment and compression testing attachment.

 

Electrical measurement and control system

 

  • Using stepping motor (AC servo system and servo motor are optional), stable and reliable performance, with over-current, over-voltage, over speed, overload and other protection devices.

  • It has the functions of overload, over-current, over-voltage, upper and lower limit of displacement and emergency stop.

  • The built-in controller ensures that the testing machine can realize the control of beam displacement and other parameters, and realize constant velocity displacement..

  • At the end of the test, it can return to the initial position at high speed manually or automatically.

  • The real physical zero adjustment, gain adjustment and automatic shift, zero adjustment, calibration and disk saving of test force measurement are realized without any analog adjustment link, and the control circuit is highly integrated.

  • Electrical control circuit reference international standards, in line with the national testing machine electrical standards, strong anti-interference ability, to ensure the stability of the controller, experimental data accuracy.

  • With network interface, it can transmit, store, print and record data, and connect with intranet or Internet.

 

Description of main functions and features of the software

 

    The software is used for testing various metals and nonmetals (e.g. wood-based panel) by microcomputer controlled electronic universal testing machine. It can complete real-time measurement and display, real-time control and data processing, result output and other functions according to the corresponding standards.

  • Sub authority management, different levels of operators have different operation authority, the menu can be operated is also different, not only the ordinary operator operation is simple, convenient, fast, but also effectively protect the system.

  • Real time measurement and display of test force, peak value, displacement, deformation and other signals. Real-time acquisition and control under Windows platforms such as Win XP, Win 7 & Win 10, etc. Accurate timing and high-speed sampling are realized.

  • The real-time screen display of load deformation, load displacement and other test curves is realized, and the observation can be switched at any time.

  • The computer storage, setting, loading and other functions of test parameters, zero setting, calibration and other operations are carried out from the software, and each parameter can be conveniently stored and transferred in, so that a host with multiple sensors can be easily switched, and there is no number limit.

  • It supports the constant velocity displacement control mode, and gives the standard reference curve in the process of debugging parameters by advanced operators, so that users can actually observe the influence of various parameters on the effect.

  • Human computer interaction was used to analyze the data. The processing method can meet the requirements of GB/T 228-2010 metallic materials tensile test at room temperature, which is widely used. It can automatically calculate the elastic modulus, yield strength, specified non proportional elongation strength and other performance parameters. It can also manually intervene in the analysis process to improve the accuracy of analysis. It can also process other data according to the standards provided by users.

  • The test data is stored in text file to facilitate users' query, and reprocessing the test data by using any general commercial report and word processing software. At the same time, it is convenient to transfer data on the Internet.

  • It can record and save the data curve of the whole process of the test, and has the demonstration function to realize the reappearance of the test curve. It can also be used for curve superposition and comparison, which is convenient for comparative analysis.

  • The test report can be printed in the format required by users. Users can choose the basic information of report output and the content of test results and curves to meet various needs.

  • The digital zero adjustment and automatic calibration of test force and deformation are realized, which facilitates the operation and improves the reliability of the machine. All kinds of parameter system settings are stored in the form of file, which is easy to save and restore.

  • It can be used in Win XP, Win 7 & Win 10 and other operating systems. The control of test process, the change of moving speed of beam and the input of parameters can be completed by keyboard and mouse, which is convenient and fast.

  • It can automatically identify and support external inching control, which makes it convenient to clamp the sample.

  • With overload protection automatic stop function, and can automatically judge the sample fracture, automatic stop.

  • According to different user requirements, the above software functions will be increased or decreased or adjusted.
