In this study, a cast Iron crankshaft of a single cylinder 4-stroke diesel engine was taken and a static analysis was conducted to get variation of stress magnitude at critical locations of the crankshaft. A model was created in CATIA of crank shaft and imported into ANSYS to carryout static analysis. Meshing of crankshaft was done; loads and boundary conditions were applied as per the mounting conditions of the crankshaft on Finite element model of crankshaft. Results obtained from the analysis were then used in optimization of the cast Iron crankshaft. Weight Optimization is achieved by varying the crankpin diameter. This requires the stress range in FE analysis not to exceed the magnitude of the stress range in the original crankshaft. The optimization process involves geometry changing without changing engine block.
