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

Figure 12

Probability density functions for the residual stress at different parts of the bearing inner ring. (a) Probability density function for the residual stress of the large end face. (b) Probability density function for the residual stress of the small end face. (c) Probability density function for the residual stress of the outer surface (the vertical test). (d) Probability density function for the residual stress of the outer surface (the parallel test).
