Precision Mechanical Design & Vibration Stability Analysis — Developed a 3D SolidWorks CAD model of an ultra-stable mechanical assembly for precision optical experiments. Conducted modal/vibration analysis to determine natural frequencies and vibration modes (including approximately 663 Hz, 2400 Hz, and 3900 Hz), identify potential resonance conditions, and evaluate the mechanical stability of the assembly. The work supported the development of a mechanically robust system capable of operating in a highly noisy environment while meeting stringent stability requirements for precision measurements.
