Steering knuckle is the main part of the steering and suspension system various link of suspension and steering are linked to it and depend on the steering knuckle. Therefore, it requires high precision, quality and durability. The strength component is always in demand for race car application. Earlier if the knuckle fails the design team used to modify the design part by trial and error method. Now we are using DFMAE method followed by experimental analysis. The two step process has been used for the same. First part involves modeling and analysis of steering knuckle by CATIA V5 R21 and ANSYS 16.0. The second step is experimental stress analysis by using strain gauge. Strain gauge is component which senses the stress acting on component and the give the result in form of stress vs time. In automotive suspension, the knuckle is the main part through the suspension wishbone link are connected and the suspension spring are on the wishbone. The hub and braking systems are mounted on the steering knuckle to complete the wheel assembly. The wheel and tyre assembly attach to the hub or spindle of the knuckle where the tire/wheel rotates while being held in a stable plane of motion by the knuckle/suspension assembly. Failure region were identified from the static and dynamic analysis and results compared to experimental analysis by using strain gauge. And this analysis carried out under all operating conditions.
