Optimización topológica en el diseño del brazo de suspensión de un vehículo compacto de tipo m1 utilizando estructuras reticulares de Lattice

Abstract

The growing demand for affordable urban mobility solutions has increased the popularity of economically accessible vehicles, such as the Kia Picanto and Hyundai Grand i10, which accounted for 14.84% of car sales in 2023, according to AEADE. In this context, topology optimization (TO) has emerged as a vital tool for developing lighter and stronger vehicle components by minimizing material usage without compromising mechanical properties, as demonstrated in redesigns like clutch forks, where mass was reduced by 24% and rigidity increased by 37%. However, TO can lead to issues such as stress concentrations and overheating, which are addressed by advanced strategies like lattice topology optimization (LTO). LTO uses microscale cellular structures to enhance stress distribution, load capacity, rigidity, and energy absorption. For M1-type vehicle suspension arms, the combined application of TO and LTO tackles challenges related to weight reduction and structural efficiency while ensuring safety and durability under applied loads, all while considering manufacturing constraints to achieve optimal configurations.
