Abstract

Using Lagrange′s equation

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.
