The monocoque is a chassis that represents the skeleton of a racing vehicle, this is the largest structure present within it, where all the components are mounted, as well as, all the loads are transmitted. In this work, this structure is formed by sandwich panels, which are generally used in motorsport areas, as well as in transportation vehicles where high rigidity is associated with low weight, these types of panels have two outer faces with a core in the middle. The present work is done around a chassis for a formula student electric vehicle for the FSIPLeiria team, where the goal is, through the analysis of the various panels, according to the competition rules, and the finite element analysis, to obtain a rigid structure that complies with the regulations and will be able to compete in the future, then a project of the monocoque geometry was designed, for the analysis of the dynamic loads, at the suspension attachment points, and torsional stiffness in order to optimize the structure’s composition. It was possible to conclude that the monocoque is a superior structure to a conventional tubular chassis, made from steel tubes, in terms of bending and torsional stiffness, however, these advantages come at a cost due to the complexity during the whole development process, as well as in production and in monetary costs.
