As Drivetrain Engineer this year, I designed and engineered the Knuckle. This component attaches the rest of the drivetrain assembly (motor, gearbox and wheels) to the chassis, through the suspension arms. It also houses the gears for a 2 stage, single speed planetary gear reduction.
Last year's gearbox looked super cool! but also had it's fair share of problems, which often required sketchy repairs. This year, the whole team focused on optimizing the second iteration, and resolving all reliability issues
The knuckle was designed in SolidWorks, and analyzed in ANSYS Mechanical using a Static Structural analysis. FEA is a super powerful tool, but only if used correctly.
Garbage in = Garbage out.
Setting up the load cases correctly was critical to design a safe and reliable part that lasts the required fatigue cycles.
I am passionate about automobiles and the engineering behind them - it's been a childhood dream of mine to work on cars. I finally got the opportunity now that I'm an adult. I spent most weekends the summer after I bought my BMW 318ti working on it - fixing electrical issues, refreshing suspension components, and repairing whatever else kept breaking. It was made in 1998 after all.
I designed, built, and tuned a pair of bookshelf speakers featuring Tectonic Audio Labs' BMR and SDW Technology.
Lots of work and effort goes into great sounding speakers, here is a summary of what I did:
Modelled using Lumped Parameter Modelling software - AkAbak
Designed using SolidWorks
3D printed with resin
Primed, painted, and finished
Measured impedance and other acoustic properties
Tuned/EQ'd in Anechoic Chamber
