Application of Cepstrum in Measurement of Vibration

HE Jun-jie;Aviation Key Laboratory of Science and Technology on Power Transmission of Aeroengine;  
The cepstrum analysis technology introduction and time domain analysis, frequency domain analysis of examples, analysis technology is easy to transfer function to distinguish fault vibration signal and system summary of inverted spectrum, edge frequency components can effectively identify the frequency modulation signal, it can greatly enhance the fault frequency component recognition ability, in high speed rotating machinery wrong, bearing or gear defects, oil whirl, friction, depression and quality of asymmetric vibration testing signal recognition has a significant advantage.
