An Automaton Fault Diagnosis Based on Shock Response Analysis

摘要：

　　Shock and vibration response is a particularly important signal to characterize the system state.This paper analyzes the reason of fault generated high speed machine, vibration response mechanism and its frequency characteristic.According to the measured vibration signals, done time and frequency domain features analysis, wavelet packet analysis and frequency domain energy analysis, put forward a kind of fault comprehensive diagnosis method with accurate and rapid identification characteristics, can adapt to the complex vibration response signal with interference and low signal to noise ratio.
