Abstract

Abstract

Nonlinear dynamics of a cracked rotor with whirling were analyzed and were compared to a rotor without whirling.Distinct differences have been found in bifurcation,amplitude,orbit and Poincare map when carrying on this comparison.Complicated dynamics may be found when a cracked rotor has its whirling speed.The results revealed may be useful in crack-early-detection and diagnosis.
