Multicasco, análisis estructural, elementos finitosResumen
El análisis estructural de un multicasco es relativamente complejo debido a que la estructura de unión entre los cascos introduce esfuerzos adicionales a los típicos de un monocasco. El trimarán de aluminio presentado en este trabajo fue diseñado en el marco del proyecto de investigación “Diseño Conceptual de Embarcación de Alto Desempeño para el Transporte de Pasajeros en la Zona Austral de Chile”. El trimarán se dimensionó estructuralmente usando los reglamentos de las sociedades de clasificación Germanischer Lloyd, Det Norske Veritas y Lloyd´s Register. Para el escantillonado obtenido con cada reglamento se creó un Modelo de Elementos Finitos y el análisis estructural se llevó a cabo para los eventos de slamming y splitting moment. Se analizaron los resultados y se determinaron las zonas de concentración de esfuerzos para compararlos con los esfuerzos admisibles y concluir si el dimensionamiento estructural responde en forma adecuada y segura a las cargas de diseño.
