Optimization of Aircraft Mid-Fuselage Structure Design Based on Parametric Modeling

Abstract:

In aircraft preliminary design, fuselage structure design is important, and to reach the lightest weight is the main target for aircraft design, especially for civil aircraft. Based on CAD/CAE technology, the paper selects a typical structure layout form of aircraft mid-fuselage to study the method of structure model quickly creation and optimization. First, it focuses on fuselage parameterized modeling method, based on CATIA secondary development technology, to create the mid-fuselage parametric model. Then, based on Patran command language, the CAD model achieves automatic meshing. Finally, selecting an appropriate strategy and using iSIGHT integrated with fuselage parametric model and finite element model, and referring to the calculated the structural response by Nastran to realize mid-fuselage structure optimization.
