Grey Relation Evaluation and Truth Value Fusion of Rolling Bearing Multisource Residual Stress

Table 10

Third fusion estimated true values of the residual stress at different parts of the bearing inner ring based on the grey bootstrap method.

	Large end (MPa)	Small end (MPa)	Outer surface (vertical test) (MPa)	Outer surface (parallel test) (MPa)
Grey bootstrap method	−918	−673	−456	−231
