Abstract

Abstract: To research the crashworthiness characteristics of the large aeroplane and numerical analysis, a finite element model for typical sub-cargo structure is established and the solution and analysis of explicit dynamics are realized. The dynamic behavior of the structural response, energy absorption and failure of the inverted and clamped sub-cargo structure under the vertical impact of 200 kg drop weight with a 7 m/s velocity are investigated. The failure mode, impact response and energy absorption and dissipation characteristics of structure are identified and analyzed during the impact process. The simulation results show that the fuselage frame components and the support assembly of sub-cargo structure are the main energy absorption structures under this crash condition. The absorption of impact energy mainly depends on the plastic deformation and failure of the structure, while the energy absorption from the fasteners joints is only about 1%.

Key words: crashworthiness, large aircraft sub-cargo structure, failure mode, energy absorption characteristics, finite element analysis
