Paper Title:
The Wavelet Transform in the AE Signal Feature Research of the Rubbing Fault Caused by the Different Pairs
  Abstract

Combine wavelet function “db10”with MATLAB band energy scale decomposition method, studied the characteristics of acoustic signals on different rubbing pair at low speed situations. The results indicate that acoustic signal generated by rubbing fault has obvious sudden; In general, the characteristics of acoustic signals induced by different rubbing pair is basically similar, so the characteristics of rubbing fault affected by rubbing pair of material is very small; The fault charac-teristic frequency is 328-420KHZ , 223-300KHZ at low speed.
