摘要
根据小波能对信号包络提取的原理对滚动轴承的振动信号进行了研究,应用基于小波原理的自信息包络提取法,同时把该方法应用于分析滚动轴承故障,证明该方法能更有效地提取滚动轴承的信号包络,适用于分析滚动轴承故障。
The rolling bearing signals are investigated in line with the principal that the Wavelet can extract a signal envelope. A Wavelet-based self-information extracting envelope method is applied.Application of the method demonstrates that the method is effective to extract the rolling bearing signal envelope and is useful to analyze the rolling bearing faults.
