MODELLING AND ANALYSIS OF UPRIGHT AND HUB FOR FORMULA STUDENT VEHICLE

The upright or knuckle attaches the wheel, brake rotor, hub, brake calliper, 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. Initially suspension is designed using lotus shark software and by using that hard points upright is modelled using Solid works software. While modelling various parameters like hub diameter, brake calliper mounts, bolt size, rim spacing is taken into consideration. The model is meshed using ANSYS and analysed based on the loads calculated using analytical method using formulae of various manures possible. 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.
