Fault Detection of a Wheelset Bearing Based on Appropriately Sparse Impulse Extraction
Convolution sparse representation (CSR) is a novel compressive sensing technique proposed in 2016 and provides an excellent framework for extracting the impulses induced by bearing faults and the unevenness of wheel tread. However, its sparsity performance on extracting impulses is sensitive to the...
