| 摘 要： | 鉴于采煤机复杂工况下微弱故障特征难以提取的问题,应用最大相关峭度解卷积(Maximum Correlated Kurtosis Deconvolution,MCKD)方法于采煤机截割部齿轮箱的故障诊断.然而,凭先验信息确定的解卷积周期,可能导致MCKD的提取效果很差.因此,在计算解卷积周期左右的一定范围内,对故障信号进...

| Abstract: | Under complex working conditions,it is difficult to extract weak fault features of the shearer.In order to solve the problem,maximum correlated kurtosis deconvolution(MCKD)was introduced to diagnose the fault of the gearbox of the cutting unit of the shearer.However,the extracting effects with MCKD algorithm were probably poor according to the deconvolution period determined by priori information.Therefore,within a certain range of the calculated deconvolution period,the optimal deconvolution fault period was determined by periodically searching for the fault signal,thus the excellent deconvolution effects with MCKD algorithm were guaranteed.Finally,the extraction of the weak fault features of the cutting unit of the shear and the diagnosis application indicated the effectiveness and the superiority of the method. |
