| 摘 要： | 基于小波信号重构与Hilbert—Huang变换，对矿井提升机进行了故障诊断研究。结果表明，采用自适应的信号处理方法，可获得故障振动信号发生的时间和故障发生的周期，定量刻画故障的频率、时间与幅值的分布，从而能够有效识别故障类型。

| Abstract: | The paper studies the fault diagnosis to the mine hoist based on wavelet signal and Hilbert-Huang transformation. The fault cycle is obtained,and the fault frequency and time-amplitude distribution can be quantified by the self-adaptive signal processing.Faults can be easily identified by this approach. |
