It is important that fissures resulting from material fatigue in rotating machines are detected in good time before the breakage occurs, which usually leads to fatal consequences.
The Set of Rotating Shaft with Crank, "MDU-SRS", consists of two shafts with different lengths, the short shaft simulates a projecting shaft end and the load is transmitted with the belt drive of the Set of Belt Drive, "MDU-SBD", whereas the long shaft is used with a protective bearing of the Set of Elastic Shafts, "MDU-SES", and a flywheel in order to study a shaft fissure in the case of an elastic rotor.
With the Set of Rotating Shaft with Crank, "MDU-SRS", a fissure with very close to real behaviors is simulated. By clamping the flange joint tightly with different forces, small temporary openings in the joint are achieved.
