Research on Structural Design of Aluminum components for Large Aircraft based on Additive Manufacturing Technology

Abstract

Laser-additive manufacturing technology can realize near-net forming manufacturing of structural parts by laser selective melting, and can overcome the limitation of traditional technology and realize the forming of complex components. Aluminum alloy has low density and high strength, and is widely used in aircraft structures. The paper introduces the research progress of laser-additive manufacturing technology, puts forward the design process of aluminum alloy structure of aircraft based on additive manufacturing technology, and illustrates the design feature extraction, topology optimization, strength analysis, test verification, etc., which provides reference for lightweight design of large passenger aircraft.
