Knowledge-driven rapid design on aircraft wing structure

In order to improve the quality and efficiency of aircraft wing structure in the preliminary design stage, modeling process of aircraft wing structure was studied. The coordinate of the structure layout and component location parameters rules were defined. Rapid modeling method of wing structure based on the template was represented. The appropriate parametric tool which can meet the development requirements of the wing structure was selected and rapid design system of knowledge-driven aircraft wing structure was developed. Knowledge of design methods, rules and expert experience was encapsulated into a template. Automatic layout of the wing structure was achieved and a layout model was generated. Solid modeling was processed separately according to the different generation logics of layout model. Parametric modeling of the geometric characteristics of the body through user-defined features (UDF) technology was accomplished and automatically instantiated on the basis of the layout model. Finally, aircraft wing box structure example was given to demonstrate that the method is feasible and effective.
