摘要
介绍了旋转机械振动、碰磨信号的采集，应用快速傅里叶变换ＦＦＴ方法对信号进行处理，提出了用声发射（ＡＥ）方法检测转机碰磨故障的新方法。在此基础上，利用先进的计算机辅助监测诊断技术研制一新型仪表，用于同时检测旋转机械的振动故障与碰磨故障，解决了以往单纯检测振动故障或单纯检测碰磨故障的难题。
A research procedure about detecting the vibration and friction fault of rotating ma-chanism is presented in this paper. A new method has been suggested to detect the machine's frictional failure by Acoustic Emission(AE),and then to detect vibration and friction simultaneously with a new instrament.The paper also introduces the way to use FFT analgsis of vibration signal by multimedia notebook computer.
