The study was undertaken with the objective of analysis of single cylinder four stroke engine of Super Splendor Crankshaft using ANSYS Software for different materials and optimize the best materials for crankshaft. The three materials used were Structural Steel, Aluminum Alloy and Nickel Chromium Molybdenum Steel. The measurement of crankshaft of bike engine was taken from bike workshop and model was generated in SolidWorks which was finally imported in ANSYS for Analysis. The stress analysis and total deformation was criteria for optimization of crankshaft materials. The comparative study was done by comparing both analytical as well as software generated results. The value of von-misses stresses of analysis is less than the material yield stress so this design is safe. From this work, the maximum stress appears at the area between crank journal and crank cheeks. By comparing von-misses stress values, Aluminum Alloy has higher strength and shows lower stress value (146.28 MPa) than other materials. Because of the more strength, Aluminum Alloy crankshaft can withstand load and is best materials for crankshaft among three.
