摘 要: The fault feature extraction is the critical role of rolling bearing fault diagnosis. This paper has proposed a bearing fault feature extraction method based on variational mode decomposition (VMD) feature energy entropy. The bearing fault signals was decomposed by using VMD, and some IMF components was obtained; Then the corresponding IMF components was selected according to the data or operation state for reconstruction; and the energy entropy value of the reconstructed signal was calculated to diagnose the fault of rolling bearing. The experiment results show that the proposed method can effectively identify rolling bearing fault types, and it can also accurately distinguish fault degrees.

故障特征提取是滚动轴承故障诊断的关键环节。本文提出了一种基于变分模态分解(VMD)特征能量熵的轴承故障特征提取方法。通过VMD对轴承故障信号进行分解,得到若干IMF分量; 然后根据数据或运行状态选择相应的国际货币基金组织(IMF)组件进行重建; 并计算了重构信号的能量熵值以诊断滚动轴承的故障。实验结果表明,所提出的方法能有效识别滚动轴承的故障类型,同时还能准确区分故障程度。
