Swarm decomposition (SWD) is an emerging signal method and has been applied in the fault diagnosis of rotating machinery. However, performance SWD highly dependent on user-defined parameter. In this article, adaptive swarm (ASWD) guided by spectral characteristic information scanner (SCIS) proposed to automatically decompose vibration into a set subcomponents. The can not only adaptively extract weak fault-related component from contaminated strong noise but also avoid problem parameter...
Variational mode extraction (VME), a novel signal decomposition method based on frequency-domain filter in essence, has recently become potential tool fault diagnosis. However, the original VME algorithm is not provided with full self-adaptation, and its performance of features subject to predefining initial parameters, including center frequency (ICF) balance parameter. To address these issues, spectral feature informed variational model (SFIVM) constructed overcome defects parameters...
