The invention provides an optimization method for a fuselage barrel section end frame shape-preserving frame and a storage medium. The optimization method comprises the following steps that 1, a fuselage barrel section three-dimensional structure model, a shape-preserving tool three-dimensional structure model and a bottom bracket three-dimensional structure model are constructed; step 2, establishing a fuselage cylinder section grid unit, a shape maintaining tool grid unit and a fuselage cylinder section bottom bracket grid unit; thirdly, constraint relations are applied to the machine body barrel section grid units, the shape maintaining tool grid units and the machine body barrel section bottom bracket grid units; 4, solving deformation results of the fuselage cylinder section three-dimensional structure model, the shape-preserving tool three-dimensional structure model and the bottom bracket three-dimensional structure model; and 5, according to the deformation result, changing the geometric form and the material type of the shape-preserving tool three-dimensional structure model, repeating the step 1 to the step 4, completing the calculation of the deformation result of the fuselage cylinder section three-dimensional structure under different shape-preserving tool geometric forms, and selecting the shape-preserving tool three-dimensional structure model with the minimum deformation according to the result.

The application relates to the technical field of building digitization, and particularly discloses a system for intelligently generating a building component of a Huizhou style based on non-heritage pattern recognition, which collects and analyzes non-heritage component images and semantic descriptions, constructs a pattern narrative knowledge set containing pattern semantic entities and relation predicates, receives target cultural implications and component form constraints, generates a semantic relation topological structure through intelligent reasoning, then instantiates the topological structure into a preliminary geometric contour according to a set of geometric form rules, then performs non-heritage visual stylization enhancement processing on the contour, finally performs multidimensional compliance verification and iterative optimization on the stylized contour, and outputs a digital building component model meeting comprehensive requirements of culture, form, aesthetics and engineering; the application solves the key technical problem of disconnection between artistic conception narration and algorithm form in a traditional generation method, and realizes intelligent and faithful innovative transformation of non-heritage patterns from cultural semantics to constructible geometry.

The application provides a cableway bridge parameterized modeling method based on geometric form finding and space topology mapping, relates to the technical field of bridge engineering digital design and modeling, and the technology comprises the following steps: constructing a calculation domain, analyzing form finding, constructing an assembly reference, component topology mapping and full model generation. The application establishes a full parameterized driving dynamic model: all geometric features of the model are driven by input design parameters and topology relations. Through preset parameter dependence relations and update sequences, the system can automatically and orderly update the whole three-dimensional model when the parameters are changed, realizes "one modification, everywhere update", significantly improves the design iteration and scheme comparison and selection efficiency, and solves the core problem of parameter and model disconnection.
