Design Optimization and Structural Analysis of an Internal Combustion Engine Crank Shaft

The crankshaft is a critical mechanical component in internal combustion engines, responsible for converting the reciprocating motion of the pistons into rotational motion to drive the vehicle or machinery. This project focuses on the design, modeling, and analysis of a high-performance crankshaft using advanced engineering tools. A 3D model of the crankshaft was developed using solid works software to achieve optimized geometry that balances strength, weight, and manufacturability. Finite Element Analysis (FEA) was conducted by using Ansys to evaluate the stress distribution, deformation, and fatigue life under dynamic loading conditions. The study also explores material selection and surface treatments to enhance durability and efficiency. The results provide valuable insights into improving crankshaft reliability and performance in modern engines, contributing to reduced mechanical failures and enhanced powertrain longevity.
