The Modular Fairing for Road Bicycle Wheels project aimed to reduce aerodynamic drag on traditional spoked wheels by designing a lightweight, snap-on fairing system. Using CAD, 3D printing, and wind tunnel testing, the team created modular components that attach securely to standard 700c wheels. Testing showed drag reduction and potential power savings of 5–10 watts at 25 mph. The fairing maintained structural stability and ease of use while improving performance. This project demonstrated practical engineering design and analysis, offering cyclists an accessible aerodynamic upgrade without replacing their wheels, and emphasized efficiency, modularity, and real-world applicability in mechanical design.
During my internship at General Dynamics, I was tasked with creating 3D CAD models of a Keyence IM-RU1 coordinate measuring machine to support the design and prototyping of custom work holdings. My models allowed for precise integration with the CMM.
This project analyzed the crankshaft of a Honda GX160 single-cylinder engine using both ANSYS simulations and hand calculations to assess its fatigue life and dynamic behavior. The crankshaft was evaluated under realistic loading derived from engine specifications. Fatigue analysis using Goodman criteria showed infinite fatigue life, supported by hand calculations on a simplified beam model. Modal and harmonic response analyses identified the natural frequencies and confirmed deformation behavior at resonance. A transient response analysis simulated real-time piston excitation, revealing minimal deflection, indicating high stiffness. The study concluded that the crankshaft operates safely under expected conditions, with simulation results aligning well with theoretical predictions, demonstrating a successful application of mechanical design principles.
