Wire Torsion Testing Machine

Application Scope:

This series of testing machines complies with GB/T 10128-2007 and is mainly used for torsional performance testing of metal materials, non-metal materials, composite materials, and structural components. The machine adopts an AC servo-controlled motor for loading output, a high-precision torque sensor for torque measurement, and a photoelectric encoder for torsion angle detection. Test results are displayed and processed by a computer. The system is equipped with high-rigidity, high-precision, high-load linear guide rails and other precision components, ensuring stable operation and accurate measurement.

Product Introduction:

1.The electronic torsion testing machine consists of a loading system, transmission system, data acquisition, processing, control, and display system, and is suitable for mechanical performance testing of various torsional elastic components, structural parts, bolts, and similar specimens.

The machine adopts a horizontal structure and is controlled by an embedded high-performance MCU controller, featuring an LCD display with a fully Chinese operating and display interface. The displayed information is clear and intuitive, and the multi-key operation combined with guided prompts allows users to complete system parameter settings easily by following habitual operating steps.

An AC servo motor combined with a precision reducer transmission system ensures uniform loading, stable operation without impact, and accurate data acquisition and control.

2.The entire machine is equipped with a fully digital data acquisition and processing system and an LCD display system, enabling multi-point measurement of specimen torsion angles. During testing, the controller performs high-speed data sampling. The system can dynamically and real-time display curves such as torque–torsion angle, torque–rotation angle, torque–time, torsion angle–time, and rotation angle–time.

The software can calculate and process torsional performance parameters specified by relevant standards, including shear modulus, specified non-proportional torsional strength, upper torsional yield strength, lower torsional yield strength, torsional strength, and maximum non-proportional shear strain. The machine supports both clockwise and counter-clockwise rotation, and after the test is completed, a manual control box can be used to return the system to the initial test position.

Product Features:

1.Equipped with a high-speed microcontroller (MCU) as the main control chip, providing fast system response and comprehensive functionality.

2.Uses a dedicated signal amplifier combined with a high-precision, high-stability voltage reference and a high-resolution digital-to-analog converter (DAC), ensuring excellent resolution and repeatability of measurement results.

3.Features an LCD display with a Chinese-language interface and parameter prompts, offering clear, intuitive, and comprehensive information display.

4.Incorporates a unique automatic operation mode with multi-point measurement capability, effectively improving testing efficiency.

5.The machine adopts a compact structural design with optimized circuit layout, providing strong anti-interference performance and high operational stability.
