    Abstract
  • A combination method of theoretical analysis, numerical simulation and model explosion test was used, the structure and stress state of airliner cabin door edge were analyzed, and the mechanical model was set up to describe the forced location of cabin door edge. Aimed at the forced location of door edge subjected to explosion impact loading, numerical simulation was put up by using the Explicit module of finite element software ABAQUS. The necessity and difficulties of door edge reinforcement were analyzed, reinforcement measures were proposed, and the results of explosion test and numerical simulation were compared. Analysis result shows that airliner cabin door edge cann't bear explosion impact loading, and must be reinforced. The mean thickness of pressure-reducing plates is 5 mm, the mean thickness of reinforcement plates is 6 mm, the total weight of reinforced members is 3.98 kg, and reinforcement measure is effective.
