WDW-5D Computer control Universal Testing Machine

1. Introduction

WDW-5D is a new generation of microcomputer controlled electronic universal testing machine. It is mainly used to test the tensile, compression, bending, shearing, peeling, tearing and other mechanical properties of various metals, non-metals and composite materials. The system adopts microcomputer closed-loop control, has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in the measurement and control of load and displacement. The equipment is suitable for metal, adhesives, pipes, aluminum, stainless steel, copper, aerospace, petrochemicals, waterproof membranes, wires and cables, textiles, fibers, rubber, ceramics, food, medical packaging, geotextiles, films, wood , Paper and other manufacturing industries, as well as product quality supervision departments at all levels. It is also suitable for teaching demonstrations in colleges and universities.
The design of the main machine of the testing machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance, no pollution, low noise and high efficiency. The design of the auxiliary equipment matches the host machine, and the structure is wedge-shaped translational, manual rotation clamping, and the sample is not subject to additional force. The clamping is convenient, reliable, and does not slip.
The test machine adopts AC servo speed control system and motor with high speed control accuracy and stable performance as the drive system; a specially designed synchronous toothed belt deceleration system and ball screw pair drive the moving beam of the test machine; Windows is the operating platform The control and data processing software based on database technology adopts virtual instrument technology to replace traditional digital tubes and oscilloscopes, and realizes the screen display of test force, test force peak value, beam displacement, sample deformation and test curve. All test operations are It can be done by mouse input on the computer screen, has a good man-machine interface, and is easy to operate; the dual-channel all-digital program-controlled amplifier inserted in the PC realizes the real physical zeroing, gain adjustment and test force The automatic gear shift, zero adjustment and calibration of the measurement, without any analog adjustment links, the control circuit is highly integrated, and mechanical adjustment devices such as potentiometers are completely eliminated. The structure is simple and the performance is reliable. The comprehensive application of the above-mentioned technologies ensures that the machine can realize closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize constant force, constant displacement, constant strain, constant velocity load cycle, constant velocity deformation cycle, etc. test. Users can use the PC expert system to independently set control modes such as constant stress, constant strain, and constant displacement, and smooth switching between various control modes. The program-controlled mode meets the requirements of the national standards GB/T228-2002 "Metal Material Tensile Test Method at Room Temperature" and GB/T7314-1987 "Metal Compression Test Method", achieving compliance with GB, ISO, JIS, ASTM, DIN and other standards Data processing, especially with good scalability, processing results can be stored on disk in the form of ASCII code. It provides convenience for the post-processing of test data such as reanalysis, database management and network transmission.
Because the test machine realizes the automatic control of the test process and the information processing of the test results, the operator can conveniently and autonomously set the test program control steps. During the tensile test, the tester can clearly observe the whole test process of low carbon steel and cast iron. Through repeated loading in different curve segments, from the force-displacement (deformation) curve, it is possible to visually verify Hooke's law and observe the phenomenon of cold work hardening. For materials without obvious physical yield phenomena, the hysteresis loop method or the stepwise approximation method can be used to determine the prescribed non-proportional extension strength. During the compression process, it is convenient to observe the compression yield phenomenon and strengthening phenomenon of low carbon steel, the compression failure process and fracture shape of cast iron. It can also detect the n value and r value of mechanical materials.
