| Abstract: | In order to analyze the fatigue life of the remanufactured crankshaft in an engineering machine, three dimensional finite element models of the original and remanufactured crankshaft are constructed separately in a MSC.PATRA of the FEM software. The static strength and fatigue strength of the original and remanufactured crankshaft are also analyzed based on these models. According to the simulation result, the remanufactured crankshaft has a high fatigue life. |
