Design and Analysis of Steering Knuckle Component

The Steering Knuckle component is the most important part of vehicle which is connected to front wheel with the help of suspension system, wheel hub and these are also connected to steering system and brake to the chassis. The Steering Knuckle component provides motion to desire directions with the help of steering system. It undergoes various types of varying load under different conditions. In Automobile industry low fuel consumption and light weight are the two main demands for the vehicle because the lighter steering knuckle resulting greater power and less vibration because of inertia is less. In this Paper we have done static analysis of steering knuckle component. The design of Steering Knuckle component is done with the help of Computer Aided Engineering (CAE). Steering Knuckle model is prepare in Creo(Pro-E) 2.0 and the static analysis is done in ANSYS WORKBENCH15.0 by constraining the steering knuckle and applying load on steering knuckle due to caliper mounting, longitudinal reaction, vertical reaction, vehicle weight and steering reaction. In this we have focused on optimizing the best use of material for the steering knuckle component and compare it, made from two material i.e. Cast Iron and Mild Steel which is recently using, and Forge Steel EN 47 which is suggested material. This result is verified by comparing with analytical calculations. Considering these results, model is modified.
