Design and Analysis of Steering Knuckle for FSAE Vehicle

Formula vehicles (FSAE) is confronting to increase vehicle performance by reducing the weight of the various components. In consideration of weight, knuckle is one of the serious things to look over it. Steering knuckle is a nonstandard or non-catalog component hooks up with the constraint wishbones, suspension, brake disc and wheel hub. It undergoes alternating loads subjected to different conditions. In this study we aim in reduction of weight in the knuckle with concession in the yield strength. Design a two different type of compact knuckle by using the solidworks software. The compact knuckle also provides desired direction to the vehicle and also reduces the unsprung mass. To make a compact knuckle enrich a rib in less stress areas. The difference in two knuckles is that the length of model 2 knuckle is more. If the length of the knuckle increases the stress acting on upper arm will be less when compared to the model 1. But in consideration of weight based on size model 1 knuckle is less weight without consideration of material. Thus our main aim is using the material with a high strength with less weight comparing with the commercial knuckle material. In this paper, proposed a two different materials one is Aluminium alloy 7075-T6 has a high yield strength and this is compared to the prepared hybrid composite material by which the material is prepared by adding 5wt%SiC and 3wt%Gr with Aluminium alloy 7075- T6. By the properties of the two material AA7075-T6 and AA7075- T6 with 5wt%SiC and 3wt%Gr is analysed in the Ansys 16.0 software. By the results through ansys, the stress and deformation is analyzed. By concluding the work by selecting less deformation and stress observed model and material.
