Objective
Design a transfer gearbox for a Baja SAE vehicle during my exchange semester at Manhattan University, connecting load and fatigue calculations to component geometry.
My role
I performed analytical sizing calculations for shafts, spur gears and bearings, then developed the assembly in Fusion 360.
Method & key decisions
I translated calculation results into native Fusion 360 parameters, entered manually in CAD. Changes to those parameters adapted the geometry of the assembly, helping connect component sizing and design iterations. The project used analytical calculations rather than finite element simulation.
Outcome & lessons
The deliverable was a fully parametric CAD assembly informed by analytical sizing. It strengthened my approach to mechanism and transmission design by keeping the relationship between assumptions, dimensions and geometry explicit.
