| Abstract: | In this paper,an important method of determining the necessary experi- mental sample length for the working device of the hydraulic shovel,the Trend-Curve Fitting Method' is discussed.A method is presented to analyze the confidence interval of pieeision for the sample length.Based on the large amount of experimental data,the two methods are verified by the load distribution analysis and fatigue life prediction for the working device of some hydraulic shovel.The whole process from the sample length determination to the fatigue llfe prediction has been programized. |
