Fault Frequency Identification of Rolling Bearing Using Reinforced Ensemble Local Mean Decomposition

Table 6

Performance comparisons for the proposed method using experimental data from ER-12K rolling bearing.

Real fault frequency	Rule of thumb			LMD + FSK			ELMD + FSK			Reinforced ELMD + FSK (proposed)
	CFF (Hz)	Error (%)	AFF	CFF (Hz)	Error (%)	AFF	CFF (Hz)	Error (%)	AFF	CFF (Hz)	Error (%)	AFF
122.08 Hz	112.50	7.85	0.003	112.50	7.85	0.004	131.25	7.52	0.001	118.75	2.73	0.002

CFF denotes the calculated fault frequency. AFF denotes the amplitude at fault frequency.
