Rediseño y análisis por elementos finitos del conjunto de inyección para un vehículo Shell Ecomarathon

Abstract

[ES] El alumno rediseñará y analizará el conducto de admisión de un vehículo de bajo consumo para la competición Shell Eco-Marathon, con los siguientes objetivos:

- Estudio previo del sistema anterior. - Estudio de la transferencia de calor del conjunto de la admisión para reducir la misma. - Estudio de optimización topológica del conjunto con objetivo de la reducción del peso del conjunto. - Rediseño del conjunto para su fabricación de forma aditiva en una sola pieza. - Estudio de CFD de la admisión de aire en el conjunto, comparando los resultados obtenidos por diversos programas de FEM - Conclusiones.

[EN] In this TFM, an injection and admission support of a Shell eco-marathon vehicle is analysed for its topological optimization, in the process the assembly is simplified so that it is a single piece that will be manufactured through a laser addition method. In this way, a geometry focused on saving weight and material can be obtained and avoiding the design restrictions that manufacturing through machining entails. The TFM is structured in four well-defined parts: Introduction, Preparation of the parts, Processing of the part and Optimization, Final part and finally Conclusions. In the first point, the TFM is delimited by listing its conditions and characteristics, and images of the engine and the old injection and intake support are provided. The second and third points focus on the preparation of the injection and intake support used until now to transform it into a single piece, to which a topological analysis is carried out. In the fourth point, a new design is made based on the results of the topological analysis, and in the last point, a static, modal and harmonic study of the piece is carried out again to analyse if it is valid.
