基于关联距离熵的齿轮箱故障诊断

Gearbox Fault Diagnosis Based on Correlation Distance Entropy

将非线性时间序列的局部投影消噪算法引入到故障诊断领域中,并应用改进的局部投影算法对齿轮箱箱体表面振动信号进行消噪,最后通过计算关联距离熵来进行齿轮箱故障诊断,实验证明,该方法能达到很好的诊断效果。

A local projection noise reduction for nonlinear time series is introduced into fault diagnosis field. The improved local projection noise reduction is applied to vibration signal of gearbox surface. Correlation distance entropy is computed. The experiment results show that this method is effective.
