基于连续小波变换的 Hilbert包络线松动部件定位方法
Hilbert Envelope Loose Part Location Method Based on Continuous Wavelet Transform
摘要
Abstract
In this paper ,combined with time-frequency analysis ,the impact signal arri-val time was determined by the method of calculating the Hilbert envelope maximum based on the analysis of impact signal by continuous wavelet transform (CWT ) ,and it was applied to grid localization . The results show that this method has strong anti-interference capacity and high locating accuracy ,and for the small mass loose parts it also can accurately locate their position .关键词
