auto torsion testing machine for matel and nonmetal, composite materials
1, the test machine Introduction
The machine is mainly used for materials and finished goods at room temperature mechanical properties of torsion testing can also be used to reverse the destruction of materials and finished products such as performance tests. Test specimens were mounted in an adjustable space between the clamps can be adapted to different mechanical properties of test specimens torsion tests. Testing machine adopts computer control operation, the software shows the measured simultaneously try to piece torque - time, twist angle - Time and torque - twist angle, torque - angle and the curve real time display angle, torque, peak torque and other parameters; test results can be stored and printing.
Executive Standard: GB / T 10128 "metallic materials at room temperature torsion test methods", JJG 269 "torsion testing machine test procedures."
2, the program description
2.1 Host
Host horizontal structure. Left end of the torque plate connecting the sensor to a fixed end and right end loaded as AC servo drive motor through reducer rotating disk drive afterburner through the torque transmitted to the specimen loading client to test torque plate, torque collecting client can move along the rail, with the to adjust test space.
2.2 Transmission
By using AC servo motors and drives, a wide range of testing procedures to ensure continuous speed adjustment and uniform load;
2.3 Detection of torque and torsion angle
High-precision torque sensor can measure both positive and negative direction of the torque; torsion angle of the output is exported via AC servo motor to ensure real and effective display angle. Through computer data acquisition and processing system, the sensor signal processing on a computer screen.
2.4 Measurement and Control Systems:
Test force measurement and control system consists of two-way symmetrical precision torque sensor, power supply, measuring amplifier, A / D converter and other components; realize computer control, data processing, display and other functions.
2.5 Test procedure
Throughout the test based on the Windows platform, use the Windows graphical interface type for the operating software, test parameters from the keyboard input, mouse operation virtual button to automatically complete all the testing process.
Test results can form a variety of report formats, easy to print, analyze test results.
