Riassunto analitico
This thesis describes the procedure to design a pillar assembly for a quadricycle prototype, done in collaboration with Carbopress S.p.A. Throughout the thesis, all the constraints due to the category of the vehicle, the design requirements, the material to be used, and the manufacturing process are presented in order to have a better understanding of the decision making during the design process. For the constraints and the design requirements, EuroNCAP standards and the regulations imposed by the European Commission for the L7e category were considered. In the design process, three different design iterations are described, showing their advantages, disadvantages, and changes with respect of the past iteration, as well as the reason for these changes. Afterwards, for the final iteration, three different finite element analyses (FEA) simulations were done with Ansys 19.2 in order to predict the behavior of the assembly under three different conditions: side crash, frontal crash, and a roll-over. For the results of the FEA analyses, the safety factor and the total deformation were analyzed to make sure that the requirements and constraints were respected.

Abstract
This thesis describes the procedure to design a pillar assembly for a quadricycle prototype, done in collaboration with Carbopress S.p.A.
