The equipment consists of industrial control cabinet, standard servo drive system, equipment bench, fixture and other parts. The equipment adopts platform structure, and the clamping part of the platform is provided with T-shaped groove; It is convenient for the adjustment of prototype and fixture and the change of various samples.

Static torsion test
Test method 1:
Fix the steering shaft to the test fixture according to the angle of the real vehicle, fasten one end of the sample, and apply a torque of 500nm to the other end. The product is not allowed to fail. Record the torque load and angular displacement curve.
Test method 2:
Fix the steering shaft to the test fixture according to the angle of the real vehicle, fasten one end of the sample, and apply a gradually increasing torque to the other end until the shaft fails completely. Record the torque load and angular displacement curve.
