| Abstract: | To achieve the fatigue life of cross sustaining bar, the stress results of finite element analysis are completed using the real measured dynamic load and material data. Applying the nominal stress method, the fatigue life calculation of the cross sustaining bar has been performed based on MSC Fatigue, the result of fatigue life is correspondent to the real service life. The fatigue analysis method with virtual fatigue analysis software is verified, and it provides reference for the optimum design and fatigue life analysis on cross sustaining bar. |

| Keywords: | cross sustaining bar fatigue life nominal stress method load spectrum S-N curve |
