| Abstract: | A study of the application of an advanced CAD/CAE system to the redesign of a load-bearing airtight bulkhead for a certain test aircraft has been performed. The CAD/CAE system was used for the three-dimensional digital modeling of the airtight bulkhead, including the three-dimensional structure model and finite element analysis model; the principle parameters required for the stiffness and strength analysis were determined by accounting for the operation environment constraints and design requirements; and the CAE system was used to conduct the stiffness and strength computation and computation result analysis for the load-bearing airtight bulkhead. Finally, the application of the system to the design change of airframe structural members was summarized. |
