dc.description.abstract© 2021 SAE International. All rights reserved.The BAJA SAE Brasil competition presents major technical challenges to its participants every year, including the design and manufacture of tubular frames according the Regulamento Administrativo e Técnico Baja SAE Brasil, RATBSB. The vehicle must have at least one of two possible bracing systems: front or rear, which differ in terms of the positioning of the main tubes for impact containment. The use of front braced frames is extremely widespread among Brazilian teams, due in part to the difficulty of designing rear braced frames, as they require more tubes and cause difficulties in accessing the engine compartment compared to the required structural configurations by international rules. The present study evaluates four structure configurations, these being the most comprehensive possible within the possibilities of the rules, defining loading scenarios coherent with possible accidents in competitions. There is the displacement of the structure and invasion of the survival cell, margin of safety of critical structural points through the Cozzone method, in addition to critical loads and linear buckling modes through their eigenvalues and eigenvectors, respectively. It was concluded that the requirements imposed by the Brazilian regulation, RATBSB, for rear bracing configurations do not bring outstanding additional security benefits in comparison to foreign configurations. A lower efficiency was also observed in relation to the safety of the 'nose' car configuration compared to the others.
