摘要
利用小波信号重构与最大熵谱估计对矿井提升机进行了故障诊断,结果表明,基于小波信号重构和最大熵谱估计的故障诊断方法具有较高的故障分辨率,能够在频域上更加合理地判断故障信号,从而正确地判断矿井提升机减速箱的早期故障。
The wavelet signal reconstruction and MESE are used in the fault diagnosis of the mine hoister. The results show that the wavelet- based signal reconstruction and MESE fault diagnosis method have a high resolving power of the mine hoister failure. At the same time, they are more reasonable to find out fault＇ s frequency, then judge mine hoister fault in the early failures.
