Il continuo sviluppo delle tecnologie di produzione spinge costantemente progettisti e ingegneri ad adattarsi ai più recenti mezzi di produzione disponibili. La piccola rivoluzione che le macchine per la produzione additiva hanno portato a tutte le industrie può combinarsi con l'adozione di sofisticati algoritmi di ottimizzazione topologica al fine di sviluppare e produrre pezzi di design mai visti prima che combinano funzionalità, efficienza ed economicità.
The continuous development of manufacturing technologies constantly pushes designers and engineers to adapt to the more recent means of production available. The small revolution that Additive Manufacturing machines have brought to all industries can combine with the adoption of sophisticated algorithms of Topological Optimization in order to develop and produce never before seen pieces of design that combine functionality, efficiency and cost effectiveness. In this work of thesis the main objective is to re-design and develop an already defined part of a car chassis assembly, while exploiting the possibilities that AM and TO can offer, and to prove that this new design can objectively compete with the one that has been created with conventional manufacturing technologies in mind. The components that have been chosen are two of the main vertical structures, commonly defined as A and B pillar, of the concept modular chassis designed for high performance GT cars by BIEFFE project s.r.l. of Modena. In the first part of the process, the part has been redesigned with the help of the CAD applications of the 3DEXPERIENCE software. The software permitted to use the old part sketches as a basis to develop the new ones, allowing considerations on the freedom of design due to AM and also provided a TO algorithm to calculate and compare different possible resulting shapes of the pillar. The obtained shapes have also been drafted with the software before being validated and exported for the subsequent part of the study. In the second part of the process the obtained shapes have been implemented in the full structure of the chassis, and its torsional stiffness has been estimated through the use of the embedded FEM analysis software. Comparisons with previously achieved performances have been made and show how the new designed chassis improves the considered stiffness, although requiring a certain increase in total mass and general complexity of the assembly.
