Optimization of Crankshaft for Weight Reduction

Abstract

The main objective of this study was to investigate weight and cost reduction opportunities for a crankshaft. The need of load history in the FEM analysis necessitates performing a detailed analysis. Therefore, this study consists of two major sections: FEM and stress analysis and optimization for weight and cost reduction. In this study a simulation was conducted on crankshaft. Finite element analysis was performed to obtain the variation of stress magnitude at critical locations. The dynamic analysis was done analytically and was verified by simulations in ANSYS. The analysis was done and as a result, critical region on the crankshafts were obtained. Geometry, material, and manufacturing processes were optimized considering different constraints, manufacturing feasibility, and cost.
