摘要
获取故障征兆是诊断系统必须解决的首要问题。应用小波变换理论提出了一种信号突变征兆提取方法,并将它应用于转台故障诊断中。实验结果表明,这种方法在信号突变征兆提取上具有明显效果。
It is a key problem for diagnosing system to acquire fault symptoms. A method of signal mutative symptom extraction is presented, in which the theory of wavelet transform is applied. Moreover, this method is used in fault diagnosis of test turntables. The experimental results show that this method has obvious effect on mutative symptom extraction.
