  2. Drive system: full digital control system drive; adjustable speed adjustment, even and stable loading.

  3. Transmission system: It adopts precision reducer to ensure the uniformity, stability and precision of transmission. Horizontal space 0~500mm Adjust freely within the enclosure.

  4. Measurement and display system: the machine uses a large-screen liquid crystal display system to simultaneously display the torque T, torsion angle θ, and test speed of the sample.

Product introduction:

1. Electronic torsion testing machine is composed of loading system, transmission system, data acquisition, processing, control, display system, etc., suitable for Test the mechanical properties of various torsion elastic elements, components, bolts, etc. The machine adopts horizontal structure, embedded high-performance single-chip microcomputer MCU Controller, LCD display, full Chinese operation and display interface, display information is intuitive and easy to read, multi-button operation, with Chinese display interface, Make your operation simpler, completely operate according to the custom prompt interface sequence, and complete the system parameter setting. Use AC servo motor, The transmission of precision reducer has the characteristics of uniform and stable loading, no impact phenomenon, and accurate data collection and control.

2. The whole machine utilizes a fully digital data acquisition and processing system and a liquid crystal display system to perform multi-point testing on the torsion angle of the sample. The controller can sample data at high speed during the test phase; during the test, it can dynamically display the torque-torque angle, torque-rotation angle, torque-time in real time, torsion angle-time, rotation angle-time and other curves; the software can calculate the

torsional performance specified by the standard: shear modulus, specified non-proportional torsion.Rotational strength, upper torsional yield strength, lower torsional yield strength, torsional strength, maximum non-proportional shear strain, etc. When the beam is closed, the manual control box can be used to control the return to the initial position of the test.
