ANALYSIS OF BREATHING OF CRACK IN THE ROTOR SYSTEM SUPPORTED BY ACTIVE MAGNETIC BEARINGS

Original language description

The presence of a transverse fatigue crack in the rotor system introduces a local flexibility. It is known, that during each revolution of the shaft the transverse crack can be opened, closed or it can breathe. In the submitted paper the model of breathing crack is using the sign of stress intensity factor along the crack edge to decide the amount of closure of crack. The distribution of stress intensity factor along the crack edge calculated at the steady-state response of rotor system on excitation bycentrifugal forces of discs imbalances is investigated through computer simulations.
