The chassis of the Formula Student car has driven me to push my understanding from nothing to a level that industry level judges are impressed by. I have put a lot of focus into understanding the loadpaths of the chassis, and I ended up creating a structure that is only 28.5kg with brackets, but with a torsional stiffness of over 4500Nm/deg
Through analysis in the 'chassis dossier' I was able to not only compare the mechanical properties, but also the cost benefits of the different iterations directly - and alongside factors such as the torosional stiffness distribution, I engineered the final chassis.
Anther point of interest of mine, is visualising how the chassis parameters can be tuned to achieve better vehicle dynamics.
To the right you can see a plot of the wheel loads of the UPR-E-04 under different magnitudes of lateral accelaration, and the chassis stiffness at the front and rear has been tuned depending on the vehicle parameters such that the inside wheel loads converge at 0N, giving us the highest cornering g's possible for the current geometry.
