This machine is mainly used for testing the torsional mechanical properties of metal materials, bolts, tools, finished products, structural components, transmission shafts, components, fasteners, and other samples at room temperature or in special environments. It can also be used for performance tests such as torsional damage of non-metallic materials and finished products. The tested sample is installed between fixtures with adjustable space, which can adapt to different tests of torsional mechanical properties of the tested sample.

Adopt high-precision torque sensor, which can measure torque in both positive and negative directions; The output of the torsion angle is collected and output by an angular displacement sensor to ensure the authenticity and effectiveness of the displayed angle. Through a computer data acquisition and processing system, the collected sensor signals are processed and displayed on the computer screen.

4 Measurement control system:

The testing machine is controlled and operated by a computer, and the software synchronously displays the torque time, torque angle time, torque angle, and torque angle curves of the tested specimen; Real-time display of parameters such as angle, torque, and torque peak.

5 Test process

The entire test process uses a window-based operating software with a graphical interface based on the Windows platform, with keyboard input of test parameters, and mouse operation of virtual buttons to automatically complete the entire test process.

The test results can be formed in a variety of report formats, facilitating the printing and analysis of test results.
