摘要
本文简要介绍了时频分析方法的发展及其在旋转机械状态监测、故障诊断领域中的应用。并以一个实际监测系统为例，对其检测信号应用时频分析的方法进行了数据处理，对用传统傅立叶变换处理的结果与采用时频分析方法处理的结果进行了对比分析．
It was briefly introduced that the development of joint time-frequency analysis and its application in rotary machines. A real monitoring system is cited here. It's vibration signals were processed with FFT and time-frequency analysis. The results were analyzed in contrast.
