Abstract
A method for detecting resonance in a rotor shaft of a turbine engine, in which a resonance frequency (Fr) of the rotor shaft belonging to a resonance band is centered on an estimated resonance frequency (Fr), is disclosed. The method including: measuring a parameter (P) for regulating the fuel of the turbine engine is measured to obtain an excitation signal; forming a spectrum of the excitation signal; comparing an amplitude of the excitation signal is compared with a resonance threshold (S) on the resonance band of the spectrum; and emitting a resonance detection alarm if the resonance threshold (S) is exceeded.
