Firstly, the UDWT is adopted for signal frequency analysis to determine the key frequency bands containing fault information; then, correlation dimension analysis of effective sub-waves is performed, and the correlation dimension threshold criterion is set up in sensi.
该方法首先采用UDWT对振动波形进行分频,并确定含缺陷信息的关键频段;再对有效子波实施关联维分析,在敏感尺度区间内设立关联维阈值判据,进行缺陷检测。
