| Abstract: | For the rear-driving screw conveyor of the shield machine, the finite element method followed by classic S-N curve is used to perform the fatigue life analysis of its shaft. With the help of the analysis, we can easily design the opti- mized structure to make sure that the screw works safely and efficiently during the whole construction process. |
