摘    要:依据Walsh变换具有分析微弱脉冲信号的优点,提出一种基于Walsh变换的滚动轴承早期故障特征提取方法。通过仿真及滚动轴承早期故障特征提取的实例分析,证明Walsh功率谱在故障特征提取中的敏感性及抗噪能力优于Fourier功率谱,具有较强的故障特征提取能力,凸显了滚动轴承的故障特征频率,能有效地诊断出轴承的早期微弱故障。

关 键 词:滚动轴承  Walsh功率谱  Fourier功率谱  早期故障特征

Abstract:According to the advantage of the Walsh Transform in analyzing the weak pulse signals,the method of incipient fault feature extraction is presented based on the Walsh Transform.Through the simulation and the analysis of incipient fault feature extraction of rolling bearings,the results show that the sensitivity and anti-noise ability of the Walsh power spectrum in fault feature extraction is superior to that of the Fourier power spectrum,and it has strong ability to extract the fault feature,the fault featu...
Keywords:rolling bearing  Walsh power spectrum  Fourier power spectrum  incipient fault feature
