Material strength tester

The Benchtop Electronic Torsion Fatigue Testing Machine (50 Nm) is a precision laboratory instrument designed for static torsion testing and torsion fatigue evaluation of various materials and shaft components. This torsion fatigue testing instrument installs the specimen between adjustable fixtures, allowing different specimen lengths and configurations to be tested efficiently.

The torsion fatigue tester is operated through a computer-based control system. During the test, the software synchronously displays the torque–time curve of the specimen, while parameters such as torque value and torque peak are monitored in real time. Test data can be stored, analyzed, and printed. The instrument supports multiple testing modes, including torque-controlled testing for torsion angle measurement and angle-controlled testing for torque measurement, as well as customized testing programs.

Application

The torsion fatigue testing machine is suitable for the following applications:

(1) Static torsion strength testing of metal and non-metal materials.

(2) Torsion fatigue life testing of shafts and rotating mechanical components.

(3) Mechanical performance evaluation of automotive and transmission components.

(4) Research testing in universities and laboratories.

(5) Quality control testing in mechanical manufacturing industries.

Standards

The torsion fatigue test instrument can be used for torsion performance testing according to common international testing methods, including:

(1) ISO 7800 (Metallic materials — Wire torsion testing)

(2) ASTM A938 (Torsion testing of metallic materials)

(3) GB/T 10128 (Metallic materials — Torsion testing method)

Introduction of Main Structure and Electrical System

(1) Main Machine:

The main machine adopts a horizontal steel plate structure. The steel plate is formed in one process to ensure high overall rigidity. The test space can be adjusted. The torque disc connected to the sensor is the torque acquisition end, and the other end is for torque loading. A precision CNC servo motor drives the loading disc to rotate through a planetary reducer, applying torque to the specimen. The torque acquisition end can move along a linear guide rail to adjust the test space and clamp the specimen. An environmental test chamber can be added if necessary.

(2) Torque Loading System:

A precision CNC servo motor drives the loading disc through a planetary reducer to apply torque evenly to the specimen, ensuring continuous speed adjustment over a wide range and uniform loading during the test process.

(3) Detection of Torque and Torsion Angle:

A high-precision torque sensor is used to collect torque in both forward and reverse directions. The torsion angle acquisition output is collected through an angle encoder. Through the computer data acquisition and processing system, the collected sensor signals are processed and displayed in real time on the computer screen.

(4) Measurement and Control System:

The entire test process adopts window-based operation software using a graphical interface based on the Windows platform. The software synchronously displays curves such as torque–time, torsion angle–time, torque–torsion angle, and torque–rotation angle of the tested specimen. Parameters such as torsion cycles, torsion angle, torque value, and torque peak are displayed in real time. Test results can be generated in report format for convenient printing and analysis.

(5) Test Process:

Select an appropriate specimen and adjust the suitable test space according to the specimen length. Place the specimen on the workbench, insert one end into the fixture body with the corresponding clamping block, slowly push the movable seat to send the specimen slowly into the fixture body at the other end, and tighten the fixture body with the clamping block using a hex wrench. After confirming that the specimen is installed, conduct the corresponding mechanical test through the torsion fatigue

measurement and control software.
