摘要
本文讨论了采用时序建模方法诊断机械故障时，建模方法、判别函数、数据修正以及信噪比等因素对诊断结果的影响。提出在可以模拟故障工况时，对判为同类的工况数据不必进行修正。对时序诊断结果与频谱分析、灰色关联分析进行了比较。
The influences of time─series modelling process,distinguish function,data amendment andS/N ratio on the diagnostic result are discussed in this paper.It is suggested that when two con-ditions are taken as the same kind,it is not necessary to amend the reference data,The time-se-ries diagnostic results are compared with those of frequency analysis and gray relativity.
