The DEMD (Differentiation-based Empirical Mode Decomposition) is employed for fault diagnoses of cracked rotor and rub-impact rotor respectively. Firstly, the algorithm of DEMD is introduced. Then, the signals of cracked and/or rub-impact rotor are processed by using DEMD and EMD methods. The comparison of the results shows that DEMD method is better than the traditional EMD method for crack and/or rub-impact detection.
