摘要
振动信号处理方法一直以来是研究的热点,对设备振动监测和故障诊断都至关重要。近年来,振动信号的处理方法得到了快速发展,但仍需不断改进和完善。对近年来的文献进行了分类总结,分别对传统方法中的幅值域分析法、傅里叶变换、相关分析和现代方法中的Wigner-Ville分布、谱分析、小波分析、盲源分离、Hilbert-Huang变换及高阶统计量分析的发展、特点以及应用进行了概述和对比分析,最后作出了总结与展望。
Vibration signal processing method has been an active research topic all the time, and the equipment vibration monitoring and fault diagnosis are crucial. Though the vibration signal processing methods developed fast in recent years, they still need to be improved and optimized. Some typical approaches referring to recent literatures are classified and summarized in this paper. The developments, features and applications are presented and discussed for amplitude domain analysis, Fourier transform, correlation analysis in traditional methods, and Wigner-Ville distribution, spectral analysis, wavelet analysis, blind source separation, Hilbert-Huang transform, higher order statistics analysis in modem methods. Finally,we make a conclusion for this paper and an overview is made to guide the future de- velopment in this field.
