A REVIEW PAPER ON MODELING AND ANALYSIS OF UPRIGHT FOR FORMULA STUDENT VEHICLE

The upright knuckle attaches the wheel, brake rotor, hub, brake caliper, Steering arm, upper and lower control arm. The design of the upright or knuckle determines the geometry on the outboard side of the suspension. The mount points on the chassis and wishbones/links form the inboard side of the suspension, and provide their own contribution to the overall geometry of the suspension and that affects the dynamics of the vehicle. The results from the analysis are taken and considered as input for the iterations on the model and the model which offers better factor of safety and less weight is considered for manufacturing. Different materials and production process are considered and compared for fabrication of upright like CNC, Aluminum casting, 3D printing. And we decided to go with 3D printing considering the point that it offers production with different materials and this method is capable of production of complex shapes which are unattainable by conventional manufacturing process. Different materials are considered for 3d printing of upright but AlSi10Mg offers better properties and the powder is relatively cheap and easily available.
