Recent trends in automobile industry is to increase vehicle performance by reducing weight of various component which in turn reduce overall weight of vehicle. Steering knuckle is critical components of vehicle which connects suspension, steering system, brake and wheel hub to the chassis. It undergoes alternating loads subjected to different conditions, without affecting vehicle steering performance and other desired vehicle characteristics. In this paper, structural analysis is carried out by considering static and dynamic load conditions to study the nature and magnitude of stresses. The objective is to reduce weight through optimization without affecting its strength, frequency and stiffness. In this study, CAD Model is generated by Catia v5, Hypermesh is used for pre-processing and for post processing Ansys is used. Shape optimization is performed by using optistruct.The total weight or mass reduction of about 4% is achieved without comprising its structural strength.
