BaidaJUSHI WDW-100E Microcomputer Control, Universal Testing Machine, Mechanical performance testing of metallic Non-metallic materials

Product Introduction

WDW-100E is a new generation of microcomputer-controlled electronic universal testing machine. It is mainly used for the testing of tensile, compression, bending, shear, peeling, tearing and other mechanical properties of various metals, non-metals and composite materials. The system adopts microcomputer closed-loop control, with a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity for the measurement and control of load and displacement. The equipment is suitable for metal, adhesive, pipe, profile, aerospace, petrochemical, waterproof membrane, wire and cable, textile, fiber, rubber, ceramics, food, geotextile, film, wood, paper and other manufacturing industries and product quality supervision departments at all levels, and is also suitable for teaching and demonstration work in colleges and universities.

The design of the main engine of the testing machine has the characteristics of beautiful appearance, easy operation, stable and reliable performance, no pollution, low noise and high efficiency. The design of the assistive device matches the main machine, and the structure is wedge-shaped translation type, manual rotation clamping, and the specimen is not subject to additional force. Clamping is easy, reliable, and does not slip.

The testing machine adopts AC servo speed regulation system and motor with high speed regulation accuracy and stable performance as the driving system; The specially designed synchronous toothed belt reduction system and the ball screw pair drive the moving beam movement of the testing machine; The control and data processing software based on database technology with Windows as the operating platform adopts virtual instrument technology instead of the traditional digital tube and oscilloscope, which realizes the screen display of test force, test force peak, beam displacement, specimen deformation and test curve, and all test operations can be completed by mouse input on the computer screen, with a good man-machine interface, easy to operate; The dual-channel fully digital programmable amplifier inserted in the PC realizes the automatic shifting, zeroing and calibration of physical zeroing, gain adjustment and test force measurement in the true sense, without any analog adjustment links, the control circuit is highly integrated, and the mechanical adjustment devices such as potentiometers are completely eliminated, with simple structure and reliable performance. The comprehensive application of the above technologies ensures that the machine can realize the closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize constant force, constant displacement, constant strain, constant speed load cycle, constant speed deformation cycle and other tests. Users can use the PC expert system to independently set control modes such as constant stress, constant strain, and constant displacement, and can smoothly switch between various control modes. The program control mode meets the requirements of the national standards GB/T228-2010 "Room temperature tensile test method for metal materials" and GB/T7314-1987 "Metal compression test method", and realizes data processing in line with GB, ISO, JIS, ASTM, DIN and other standards, especially with good scalability, and the processing results can be stored on disk in the form of ASCII code. It provides convenience for post-processing such as re-analysis, database management, and network transmission of test data.

Performance and characteristics

1. The use of AC servo motor and AC servo speed regulation system to control the test process, the control accuracy and quality are greatly improved, smooth, efficient, low noise (basically no noise at low speed) and the control speed range is greatly widened (0.05-500mm/min), which is not only conducive to the low-speed test of conventional materials (metal, cement, concrete, etc.), but also conducive to the high-speed test of non-metallic materials (rubber, etc.), and can also be used to quickly adjust the test space when no load to save auxiliary test time. The test speed meets the current test speed requirements of all conventional metal and non-metallic materials in China.

2. The reduction mechanism composed of synchronous tooth belt and precision ball screw pair "strong" joint hand makes the structure simpler and brighter, the transmission efficiency is greatly improved, and the height of the lower worktable and the height of the main machine are also reduced, and the appearance is more coordinated.

3. The dual space structure independent of tensile and compression is adopted, which is easy to operate and avoids the troublesome need to replace different test accessories when tensile and compression bending are in the same space.

4. Sensors of different specifications can be configured according to the requirements, so that the test range is greatly widened to meet the measurement requirements of different test loads.

5. The main machine adopts a fully sprayed molding shell, which is generous and beautiful.

6. Adopting advanced control technology, it has three closed-loop control modes of stress, strain and displacement, and can automatically switch between each control ring, and realize a smooth transition without impact when switching between each mode, and can simultaneously display the test force, peak, displacement, speed, test state, test curve, etc.

7. It can control and maintain the rate of test force, deformation and displacement.

8. It can realize the fast/slow lifting and lifting adjustment of the beam when the specimen is clamped, and the operation is flexible and can be switched at will.

9. It has the function of returning to the initial position after the test is over, which is efficient and fast.

10. It has perfect limit protection functions, overload protection, overcurrent protection, automatic shutdown of test breaks, etc., which is reliable and safe.

11. Build a powerful test database, and the test data can be saved, queried and called at any time.

12. Provide a variety of report printing interfaces, users can edit any format of the report according to their needs, and print it out;

13. The whole control system has high cost performance and high reliability.
