Study on Failure Diagnosis on Hoist Principle Axis Based on Wavelet Packet Analysis.

基于小波包理论,针对提升机主轴的振动信号进行了时频域分析。利用特定频段的信息进行故障诊断,并通过对实验数据的分析论证了该方法的正确性和有效性。该研究为对提升机主轴的振动信号进行处理,进而实施故障诊断提供了有效的方法。

The vibration signal of the mining hoist's principle axis has analyzed based on wavelet packet theory in Time-frequency field. The authors can acquire failure diagnose by analyzing special parts, which has been confirmed to be accuracy and effectiveness by the experimentation data. The means provides a feasible technique support for failure diagnose of principle axis.
