平稳和非平稳振动信号的若干处理方法及发展

Development in Vibration Signal Analysis and Processing Methods

回顾了稳态或准稳态振动信号处理方法中的离散频谱分析与校正、细化选带频谱分析、解调分析和高阶谱分析 ,非平稳振动信号处理方法中的转速跟踪分析、短时傅立叶分析、Wigner- Ville分布、小波分析和 Hilbert-Huang变换的发展历史 ,论述了各类方法的原理 ,分析其特点和在工程中的应用 。

In this paper the development history of stationary and non stationary vibration signal processing methods are reviewed. The principle of each method is discussed. Their characteristics and application in engineering are analyzed. Future development is suggested. The stationary vibration signal processing methods include discrete spectrum analysis and correction, zoom spectrum analysis, demodulation analysis and higher order spectrum analysis. The non stationary ones include rotating speed tracking analysis, short time Fourier transform, Wigner Ville distribution, wavelet analysis and Hilbert Huang transform.
