Adaptive TQWT filter based feature extraction method and its application to detection of repetitive transients被引量：6
《Science China(Technological Sciences)》2018年第10期1556-1574,共19页KONG Yun WANG TianYang CHU FuLei 
supported by the National Natural Science Foundation of China (Grant Nos. 51335006 & 51605244)
The local defect in rotating machine always gives rise to repetitive transients in the collected vibration signal. However, the transient signature is prone to be contaminated by strong background noises, thus it is a...
