Liu Xiandong, Li Qihan, Wang Deyou. Dynamic Model of Dual-Rotor System with Rub-Impact Fault Between Rotor and Stator and its Feature of Wavelet Transform[J]. 2000, 15(2).DOI:
the dynamic equation of dual rotor system with rub impact fault of some type of aeroengine is established
and emulations of this fault is completed through numerical calculation.The spectral analysis and wavelet transform are also made
and the conclusions are drawn that the dynamic model of dual rotor system with rub impact fault is valid and the wavelet transform is a very effective tool to diagnose this fault.
