Bearing Fault Diagnosis Based on Parameter Optimized VMD and ELM with Improved SSA

Aiming at the problem that the initial fault signal of rolling bearings is weak and the fault characteristic is difficult to extract, this study proposes a rolling bearing fault diagnosis method based on variational modal decomposition (VMD) for adaptive parameter optimization based on the improved...
