A novel ITD-GSP-based characteristic extraction method for compound faults of rolling bearing

•Intrinsic Time-scale Decomposition and Graph Signal Processing is integrated.•A PR component with minimum Laplacian Energy index is chosen.•The ITD-GSP can precisely provide the characteristic frequency of compound faults.•The ITD-GSP algorithm is insensitive to the installation direction of sensor...
