Steering knuckle is an indispensable part of an automobile vehicle, integrating different subsystems like suspension, brakes and steering. Being the pivot point of the vehicle it undergoes diverse stacking under rigorous conditions resulting in failure of the component. The objective of this paper is to perform static structural analysis on the knuckle under diverse loadings. This is achieved by designing a generic steering knuckle of a car in Autodesk Fusion 360 and performing the finite element analysis using Autodesk Nastran. The research is carried out under stressful loadings from cornering, accelerating, braking and bump maneuvering. The analysis is tested out for various materials to obtain the best strength to weight result.
