The crankshaft, sometimes casually abbreviated to crank, is that part of an engine which translates reciprocating linear piston motion into rotation. It typically connects to a flywheel, to reduce the pulsation characteristic of the four stroke cycle, and sometimes a torsional or vibrational damper at the opposite end, to reduce the torsion vibrations often caused along the length of the crankshaft by the cylinders furthest from the output end acting on the torsional elasticity of the metal. The main objective of this project was to investigate weight and cost reduction opportunities for performing a detailed loading analysis. Therefore, this study consists of stress analysis in this project a module of the Crankshaft was designed in CATIA and analysis was conducted a forged steel crankshaft. The need of load history in the FEM analysis necessitates on crankshaft in ANSYS. Finite element analysis was performed to obtain the variation of stress magnitude at critical locations. The pressure volume diagram was used to calculate the load boundary condition in the model, and other inputs were taken from the engine specification chart. The analysis was done for different engine speeds and as a result, engine speed and critical region on the crankshafts were obtained. Stress variation over the engine cycle in the analysis was investigated.
