| Summary: | In view of problem that fault feature of coal mine motor signal was difficult to extract, EMD filter method was proposed to apply to vibration signal analysis of coal mine motor. By analyzing distribution characteristics of characteristic frequency of motor fault, noise in vibration signal was filtered out through different approaches of EMD filtering. Field application results show that the proposed method can effectively reduce noise and improve signal to noise ratio. |
