| Abstract: | Calculating methods of the mininum and maxinum fatigue life scatter factor on the condition are deduced and established that fatigue life is with the same distribution as three parameters weibull distribution are deduced and established,computing and decucing process of the methods proposed are elucidated.Based on some calculating examples,effect of three parameters of Weibull distribution on the minimum and maximum fatigue life scatter facror is presented. |
