Descrizione del progetto
Rivoluzionare il panorama della produzione aerospaziale
La tecnologia di produzione additiva (AM) ha le potenzialità per rivoluzionare il panorama della produzione aerospaziale, ma vi sono ostacoli considerevoli che ne impediscono l’attuazione pratica. In questo contesto, il progetto AddMan, finanziato dall’UE, affronterà il problema della non uniformità delle proprietà meccaniche tra i componenti realizzati con la tecnologia AM e quelli realizzati con metodi di produzione tradizionali. Inoltre, elaborerà metodi innovativi di ottimizzazione della topologia e stabilirà linee guida per la tecnologia AM. Verranno formulate anche diverse strategie successive alla produzione ed economicamente vantaggiose per i componenti AM. Questi progressi mirano a snellire la produzione aerospaziale ottimizzando i componenti del sistema per ridurne il peso e i costi, rispettando al contempo i requisiti di sicurezza legati alle loro proprietà meccaniche. Riducendo peso e costi e rispettando rigorosi standard di sicurezza, AddMan annuncia una nuova era di efficienza e innovazione nell’industria aerospaziale.
Obiettivo
Additive manufacturing (AM) is a technology by which physical objects can be built directly from 3D Computer Aided Design (CAD) data, and is widely acknowledged as an enabler for revolutionizing the manufacturing landscape. It replaces traditional production methods like casting and machining, and enables essentially arbitrary geometric shapes to be produced. Although significant progress has been made on AM hardware development, there is a lack of efforts regarding material characterization, design tools and methods to efficiently bring AM to practical use in the aeronautical area. In particular, Topology Optimization (TO) – a finite element based design method – is an unusually evident and potentially fruitful technique for designing AM structures. However, the mechanical properties of AM components differ substantially from the properties of the same components produced by conventional methods, and AM components can have complex shapes, such as grid-like structures, that cannot be achieved by using conventional production methods. Therefore, the AddMan project deals with:
• Material characterization by establishing fatigue properties and geometry dependent material behavior as well as AM specific build requirements
• Development of novel TO methods, as well as CAE methods for metal AM which make use of the material properties generated in AddMan
• Development of Design for AM-guidelines that are implemented in an automated knowledge based engineering framework including connection between TO and flexible parametric CAD models, to enable holistic product optimization and
• Development of a cost effective post-processing strategy for AM components in order to increase fatigue performance.
These developments build towards the overall aim of enabling aerospace industry to efficiently redesign and manufacture optimal system components for reduced weight and costs while meeting the prevailing stress and fatigue requirements and regulations.
