Summary:

Cepstrum analysis method is an important part in the area of modern signal processing subject, which has a good application in noise source identification. The paper uses cepstrum method to analyze noise and vibration signals of diesel engine, separates and extracts periodic source signals with characteristic of non-harmonic order from complex spectrum waveform, and then identifies the contribution of each component to the spectrum with characteristic of non-harmonic order by analyzing noise and vibration signals of each component. The result shows that cepstrum analysis method can extract source signal from the complex spectrum waveform effectively, thus facilitate the identification of noise and vibration sources
