摘要
循环平稳信号处理学科的引入,丰富了机械设备故障诊断的内容。本文总结了循环平稳信号处理在机械设备信号特征提取和故障诊断领域的研究概况,分析了该方法目前所存在的问题,最后简要指出了循环平稳信号处理在机械设备故障诊断中应用的发展方向。
In recent years, the machinery fault diagnosis has been improved by the application of cyclostationary signal processing. In the paper, the application of cyclostationary signal processing in machinery fault diagnosis is summarized, the advantages and disadvantages of the method are discussed, and its widely application foreground is pointed out.
