Abstract
This study develops and validates a suspension model for a Formula SAE race car, aiming to enhance performance optimization and system integration. The vehicle's dynamic response was modeled using a seven-degree-of-freedom (7DoF) state-space vibration framework coupled with a two-dimensional, double-track yaw model. Experimental modal analysis was employed to validate the computational models, involving bump and hammer tests to identify dynamic parameters such as natural frequencies and damping ratios. The circle fit method was used to estimate damping ratios and natural frequencies from Nyquist plots and was critical for identifying closely spaced modes.
