The subsurface stress is solved by ANSYS. Based on the stress life model of Zaresky, the effects of the rough surface parameters, such as RMS(root mean square root), skewness, and kurtosis on relative fatigue life of the thin walled rotary table bearing are studied.

Experiments show that the generalized approach of moment estimators of risk premiums lead to better results on individual assets over historical averages.
