Tuning Fork Modal & Frequency Analysis

This project examined the vibrational behavior of a mechanical component through modal and frequency analysis. A tuning fork was designed in SolidWorks using defined geometric constraints and assigned stainless steel material properties to reflect realistic mechanical behavior. The objective was to determine the natural frequencies of the system and understand how geometry influences resonance characteristics.

A frequency study was conducted using SolidWorks Simulation, with the handle of the tuning fork fixed to represent a realistic constraint condition. Five natural vibration modes were extracted and analyzed, each corresponding to a distinct deformation pattern. Mode shapes were visualized through superimposed deformation plots and animation outputs, allowing for clear interpretation of vibrational behavior.

The analysis showed that longer prong geometry resulted in lower natural frequencies, producing a low-pitch response suitable for applications such as medical diagnostics, instrument tuning, and educational demonstrations. Frequency values were evaluated alongside deformation patterns to assess the tuning fork’s practical use and resonance sensitivity.

This project highlights the importance of understanding natural frequency and resonance in mechanical systems, particularly for components subject to cyclic loading or vibrational environments, where improper design can lead to fatigue or failure.
