Abstract:Abstract.Compared with the widely used straight front crack model, an elliptical front crack has been found to be more accurate and realistic for modeling the transverse surface crack in rotating machinery. When the shaft rotates, the elliptical crack opens and closes alternatively, due to gravity, and thus a "breathing effect" occurs. This variance in shaft stiffness is timeperiodic, and hence a parametrically excited system is expected. Thus, the parametric instability of a rotating shaft containing an ellip… Show more
