【摘要】 本文针对滚动轴承出现故障时产生的振动信号具有非平稳信号的特点,通过小波包变换提取故障信号的特征向量,采用Fisher判别分析对提取的特征向量进行故障分类。实验结果表明所提方法的有效性。更多还原

【Abstract】 In this paper,to deal with the non-stationary vibration signals generated by a fault in rolling bearing,the author present a method that extract some feature vectors from the fault signals by wavelet packet transform and apply Fisher Discriminant Analysis(FDA) to classify faults in rolling bearing.The experiments show that the effectiveness of the proposed approach..更多还原
