摘　　要：小波分析是获得广泛应用的信号处理新技术。这里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。Wavelet analysis is the widely used method for signal processing, in this paper, the rolling bearing signal is investigated according to the principal that the Wavelet can extract the signal envelope. A Wavelet-based self-information extracting envelope method is applied. Application fo the method demonstrates that the method is effective to extract the rolling bearing signal envelope and is useful to analysis the rolling bearing faults.
