Throughout development of fault diagnosis , in order to obtain good diagnosis result , processing of fault data is essential , and for sake of good analysis effect , method is important too 纵观故障诊断的发展历程,要想取得好的故障诊断结果,故障数据的分析是相当重要的,而要取得好的分析效果,所采用的方法也是很重要的。
Throughout fault diagnosis development we could see that it is essential to have signal preprocessing and fault signal analysis in order to obtain accurate result during fault diagnosis while methods to implement are just as important 纵观故障诊断的发展历程,要想取得好的故障诊断结果,数据预处理与故障数据的分析是相当重要的,而要取得好的分析效果,所采用的方法也是很重要的。
