从振动信号处理角度阐述了滚动轴承故障诊断的诊断流程,总结了时域分析、频域分析(包括倒频谱分析、包络分析和谱峭度法)、小波分析、循环平稳信号分析4种主流的滚动轴承故障特征信号提取处理方法最新研究进展。并在此基础上,进一步指出了该技术的发展方向。
From the perspective of vibration signal processing, the diagnostic procedure of rolling bearing fault diagnosis is expounded. The main four kinds of analysis methods, namely time domain analysis, frequency domain analysis (including cepstrum analysis, envelope analysis and spectral kurtosis), wavelet analysis and cyclostationary signal analysis The latest research progress on fault signal extraction and processing method of rolling bearing. And on this basis, further pointed out the development direction of the technology.
