The system is suitable for torsion fatigue test of metal connecting rod of various sizes and specifications.

Adopts servo motor as the torsion power which can provide rated torque of more than 100,000 N/m. 

Automatic feed, automatic loading, and automatic unloading.

Automatically collecting the value of torque and rotation angle. And it can realize closed-loop control and set with arbitrarily. Which also can through the computer for real-time record and storage, and data reduction with perceptual intuition of test results.

The system has the mark recording device and the QR code function, which can scan the QR code on the surface of parts.  Linking the info of QR code to recording system that can corresponding the specimen data and torque testing for further tracing.
