Abstract-

This paper offers an extensive study on the force and stress analysis, material substitution and structural optimization of a single-cylinder engine crankshaft. In an internal combustion engine, the crankshaft performs a critical function by converting the reciprocating motion of the pistons into rotational motion. The main aim is to improve the crankshaft's performance by optimizing its structural integrity and material composition in a way that it remains durable and efficient. Finite Element Analysis (FEA) has been performed by ANSYS to analyze stress distribution and deformation during operating conditions. Moreover, various materials have been studied to increase fatigue resistance and optimize the strength-to-weight ratio.
