Análise de otimização topológica para o projeto de um chassi multitubular de veículo elétrico de pequeno porte

Abstract

Topological optimization is a method that aims to find a model with the best mass distribution, taking into account fixtures, applied loads, mesh, and a specific domain. This method is one of the consequences of the use of the finite element method, being highly versatile and widely used today due to its comprehensive analysis capability and efficiency. The objective of this work is to propose a chassis for an extension project allocated at UTFPR-GP, which is developing a prototype electric car to participate in the Shell Eco Marathon energy efficiency competition. For this reason, a chassis with an optimal mass distribution that allows material removal without compromising the required strength of the chassis is sought. To achieve this goal, topological optimization was chosen as an approach. The main objective of this work is to reduce the mass of the chassis in relation to the model previously designed by the team, aiming at a significant improvement of this part. This is justified by the fact that the chassis represents a substantial portion of the prototype's total mass. The project in question aims to participate in the Shell Eco Marathon competition, which is a sustainable competition promoted by Shell. In this competition, teams from several universities from Brazil and other countries come together with the objective of traveling the longest distance with the least energy consumption in their respective prototypes. In this way, the project contributes directly to research and development in the technological and sustainable sphere, besides being aligned with the Sustainable Development Goals related to accessible and clean energy, industrial innovation and infrastructure, and sustainable cities and communities.
