Comparison and analysis of two auditory models faced to mechanical faults diagnosis

摘要：

　　Auditory model is a signal analysis system with simulating the mechanism of the human auditory system,and it is not only suitable for speech signal but also vibration signal for mechanical faults diagnosis.In this paper,the work of analysis and comparison for EA and ZCPA auditory mod el is done.The reason and characteristics of simulation mode of auditory nerve in two auditory mod el is illustrated.By analyzing vibration signals of different rotor faults,the performances of distingui shing different faults and stability for one kind fault for two models are compared.The results show that ZCPA model is more flexible and stable.
