故障矢量诊断法

FAULT VECTOR DIAGNOSIS

本文基于振动故障信息的矢量特征，提出故障矢量诊断法用于诊断转子类故障，并解决信号处理中产生的问题，文中列举了两个诊断实例，诊断结果表明：故障矢量诊断法是转干系统故障的定量、定位诊断的有力工具。

Based on the vector characteristics of fault information in vibration,the fault vector diagnosis is proposed and the key problem in its signal processing is solved in this paper. The proposed diagnosis technique has been applied to recognize balance fault and bearing fault in a rotor system by the combination use of wavelet analysis.The technique offered is a useful tool to diagnose fault both in degree and location.
