Abstract

The Formula 1 Halo is a lifesaving technology in the engineering of motorsport vehicles, as it offers protection to the driver without compromising the motorsport performance. This is a structural, aerodynamic and vibrational examination of the F1 Halo that incorporates the multidisciplinary design validation. The Halo is verified to meet the requirements of FIA safety with maximum stress of 399.14 MPa (yield strength: 1030 MPa) and deformation of 2.687 mm (limit: 3.0 mm) under 125 kN vertical and 0 separation forces. Calculation fluid dynamics demonstrates 0.368-0.841 coefficients of aerodynamic drag at 30 m /s and 80 m /s and forces are about 1-2 percent of total drag on the vehicle. The modal analysis determines six natural frequencies that are between 63.81 Hz and 373.9 Hz, which proves that they effectively separate resonance frequencies that are associated with natural frequencies and those involved in operation. Grade 5 Titanium (Ti-6Al-4V) showed a high-end performance feature, which proved the structural performance and aerodynamic viability. This combined method shows that the strict computational design can prove the multi-objective design optimization of safety-critical.
