This document summarizes the design and optimization of a wheel hub for a Formula ATA race car. The goals were to reduce weight while maintaining strength. The original hub weighed over 500g and the redesigned hub achieved a 50% weight reduction through material selection and design optimization without losing stiffness. Finite element analysis was used to simulate loads on the hub from acceleration, braking, and side impacts. Calculations were done to size wheel bolts, brake disk bolts, and design petals and knuckles. The optimized design had less stress concentration and was less prone to failure than the original. In conclusion, the redesign significantly reduced unsprung mass which will improve acceleration and traction without compromising suspension geometry or behavior.
