- Uma análise de otimização estrutural do sistema de suporte de rodas de um veículo espacial utilizando técnicas avançadas de discretização sem malhaPublication . MONTEIRO, RUI PEDRO NUNES; Belinha, Jorge Américo de Oliveira Pinto; Rodrigues, Daniel Espírito SantoSpace exploration has consistently been a stimulator for technological advancements, driving innovations in various engineering fields and pushing the boundaries of what is possible in extreme environments. In particular, the optimization of rover components for extraterrestrial missions has become a critical area of focus, as these devices must combine lightweight designs, high durability, and adaptability to harsh and unpredictable conditions found on celestial bodies such as the Moon and Mars. This work explores the potential of advanced numerical methods, specifically the Radial Point Interpolation Method (RPIM) and the Natural Neighbour Radial Point Interpolation Method (NNRPIM), for structural analysis and design optimization when paired with Bio-Inspired Remodelling Algorithm (BIRA). These meshless methods present significant advantages over traditional Finite Element Methods (FEM), including the ability to handle large deformations and complex geometries without mesh distortions. This thesis culminates in the analysis of the Perseverance rover’s component that connects the wheel with the suspension. As a result, this work proposes six optimized models that present stiffness values significantly higher than the original model.
