In the high-stakes world of Formula One competition, accidents are a sad reality. The primary causes of these accidents are violent overtaking, high speeds, and environmental factors. All of these causes result in accidents, such as a car colliding head-on with barricades, two automobiles colliding, a car skidding on a wet track, etc. Driver safety must be improved, and accidents of this nature must be avoided. One such safety elements that needed to be considered when designing the racing vehicles is the impact attenuator.This research paper presents a comprehensive approach to the design and analysis of an optimized custom Step Impact Attenuator tailored to meet the stringent requirements set forth by the FSAE regulations. The research paper proposes the development of a carbon fiber step impact attenuator design specifically engineered for FSAE applications. The research methodology involved analytical quantitative research, leveraging computer simulations to iteratively optimize the design. Detailed crash simulations were performed in ABAQUS, enabling the analysis of force-displacement curves, energy absorption capabilities, and anti-intrusion plate displacement. The proposed solution offers enhanced driver safety through superior energy absorption capabilities, achieving 12.024 kJ of energy absorption while maintaining an anti-intrusion plate displacement within permissible limits. This approach demonstrates the potential of advanced composite materials and computational simulation techniques in developing more effective safety systems for high-performance racing vehicles.

Keywords: Step Impact Attenuator, Carbon Fiber, Anti-Intrusion Plate, Crash Simulation, ABAQUS, FSAE.
