Main use:

NDW series microcomputer control electronic torsion testing machine is composed of a loading system, transmission system, digital data acquisition and processing system and computer measurement and control system which is suitable for display, metal materials, non-metallic materials, composite materials and components of the torsional performance test.

It features:

1, the host: the use of horizontal structure, the main structure of the frame structure to ensure that the rigidity of the whole. The main drive shaft, fixture with high quality steel, to ensure its service life. The installation and disassembly of the sample is convenient and quick. Chuck of the mobile terminal by using precision heavy rail, which can move freely, will try to minimize the axial tension member.

2, drive system: by the import of all digital AC servo control system drive, speed adjustment range, load uniformity, stability.

3, transmission system: the use of precision reducer drive, to ensure that the transmission of uniform, stable and transmission accuracy. Horizontal space 0 ~ 600mm range of arbitrary manual adjustment.

4, measurement display system: This machine adopts photoelectric encoder to collect samples of torsion angle, high precision torque sensor acquisition of torque, high precision rotary encoder to measure the torsional deformation of the sample. The computer screen shows the torque, torsional angle, torsional deformation and all kinds of curves.

5, software system:

5.1, control mode using intelligent expert system, the user can according to their actual requirements of the preparation of the test process control method to complete the test.

5.2, Windows2000/XP full Chinese interface, man-machine dialogue mode. All experiments are done by using CRT, computer keyboard and mouse, computer screen test torque T, torsion angle, test curve (torque time curve, torque angle curve and angle time curve) test machine working state.

5.3, the size of the curve coordinates can be adjusted according to the actual test data.

5.4, print a variety of output test report format (report format can be Excel or Word format output).

5.5, in compliance with the JB/T9370 - 1999 "torsion testing machine technical conditions" and GB10128 - 1988 "metal room temperature torsion test method" data processing requirements.

5.6, can test the shear modulus G value, yield, yield point of s tau tau tau SL Su, lower yield point, the torsional strength of B etc.. Torque and twist angle of the automatic tracking measurement, and display the test curve. Torque value, twist angle and torsion speed of display test. After the test, automatic test data processing, can automatically calculate the material provisions of the shear modulus G and non proportional torsion stress P, yield strength, yield point, lower yield point Su tau tau SL, torsional strength and other performance parameters of B. According to user requirements can be arbitrarily prepared report format and print test report.

5.7, the process of simulation can be realized.

5.8, testing machine can achieve continuous loading and under any load to maintain the load of two kinds of functions. There is no shock and vibration in the test process, which has good stability of reading.

5.9, can be arbitrary number of test curves superimposed contrast, output printing.

5.10, can be digitally adjusted and calibrated.

5.11, the test data using database management, easy to query and maintenance.

5.12, the operation of the software system can achieve three level user management, safe, convenient, fast.
