AUTOMOTIVE STEERING KNUCKLE

Abstract

The Automotive Steering Knuckle project focuses on the design and development of a steering knuckle, which is a critical component of an automobile suspension and steering system. The steering knuckle connects the wheel assembly to the suspension and steering components and helps transfer steering forces, braking loads, and vehicle loads between these components. Therefore, its design must provide adequate strength, stiffness, durability, and reliability while maintaining low weight. In this project, a detailed 3D CAD model of an automotive steering knuckle is developed by considering important design parameters such as overall dimensions, mounting holes, wheel hub location, suspension connections, steering arm, fillets, and material properties. The geometry is designed to withstand different loading conditions experienced during vehicle operation. The developed steering knuckle can be evaluated using finite element analysis (FEA) under static loading conditions. The analysis can determine important parameters such as Von Mises stress, total deformation, strain, and factor of safety. These results help identify critical regions and verify whether the component can safely withstand the applied loads. The CAD model and simulation results can also be used to improve the design by modifying the geometry, material, thickness, and reinforcing features. This helps achieve an appropriate balance between strength and weight. Overall, the project demonstrates the application of CAD modeling and structural simulation in the development of a reliable automotive steering knuckle. The designed component can serve as a foundation for further optimization, fatigue analysis, dynamic analysis, and manufacturing to improve vehicle safety, performance, and durability.
