Abstract

The invention belongs to the technical field of structural design, and particularly relates to a dimensionality reduction design method for a specially-shaped curved surface functional structure. According to the technical scheme, a dimensionality reduction design idea is utilized, a three-dimensional special-shaped curved surface appearance structure is expanded into a two-dimensional equivalentgeometric model, parameterization design of a functional unit is carried out in the two-dimensional geometric model, finally, the two-dimensional model containing a functional unit configuration is mapped back to an original curved surface, and a three-dimensional special-shaped curved surface functional structure is formed. The method has the advantages that the problem of overlarge calculation amount of directly carrying out functional unit configuration design in the three-dimensional special-shaped curved surface structure on the airplane is solved, an efficient design approach is providedfor special-shaped curved surface functional structure configuration design, meanwhile, the design difficulty and calculation requirements are reduced, and the method is suitable for functional structure design of the special-shaped curved surface appearance.

Description

technical field [0001] The application belongs to the technical field of structural design, and in particular relates to a method for dimensionality reduction design of special-shaped curved surface functional structures. Background technique [0002] In order to improve the lift-to-drag ratio of future aircraft, structures such as nose cones and wing leading edges need to adopt sharper and thinner aerodynamic shapes, which will cause a sharp increase in the number of special-shaped curved surface structures on the aircraft. The configuration design of functional units in curved structures presents great challenges. Existing structural design is directly based on the geometric shape through the cutting method to realize the structural design of functional units such as pipelines. On the one hand, the geometric drawing of the functional units in the three-dimensional special-shaped surface structure is very difficult. On the other hand, the functional unit in the three-dimens...
