| Abstract: | This paper introduces the sound array signal acquisition model. Combining with Gerschgorin＇ s disk theorem and MUSIC spectrum algorithm, a new method of motor noise data acquisition based on microphone array was put forward to diagnose motor fault. Finally, the fault motor was correctly diagnosed through collecting noise data and processing them with Matlab software. |
