Diagnosis Method for Sparse Optimization Based on Multi-step Grid Search of Bearing Coupling Faults

Diagnosis Method for Sparse Optimization Based on Multi-step Grid Search of Bearing Coupling Faults

Under the unbalance-bearing coupling fault of the rotor system, the unbalance fault features and bearing faults modulate each other, and the weak fault features are easily submerged by the strong fault features and strong noise components. Thus, a multi-step grid search optimization sparse diagnosis...
