Since the cyclostationarity in vibration signals is the key to judge the rotating machine health state, spectral harmonics-to-interference ratio (SHIR) has been used to construct single node feature learning network (SHIR-based blind deconvolution, BD-SHIR) to realize condition monitoring of machine. However, BD-SHIR still has several obvious limitations, including the need for prior fault informa...Show More
Decomposition techniques generally have two limitations. First, for adaptive correlated kurtogram and variational mode decomposition, etc., the definition of the decomposition target has no direct relationship with the features of fault impacts, i.e., the decomposition is not guided by health indices used to characterize bearing faults, resulting in fault impacts cannot be completely separated fro...Show More
