The dynamic behavior of a cracked rotor has been theoretically analyzed by many researchers. In this paper, an experimental confirmation of the theoretical results is sought, especially for the nonlinear dynamic behavior of the cracked rotor. The crack in the rotor was simulated by a real fatigue crack, instead of a narrow slot. It can be seen from the orbit and spectrum of the rotor’s center that the effect of the crack becomes obvious only if the crack is deep enough. The experimental result conforms to theoretical analysis very well.
