Abstract

The invention provides a modeling method for fitting a generalized cylinder curved surface based on a water bomb origami derived structure, which comprises the following steps of: firstly, mapping an optimized origami grid model from a three-dimensional state into a two-dimensional plane, and performing linear regression processing through vertex information to achieve the purpose of model precision; and constructing a three-dimensional grid model by the processed data to maximize the unfolding constraint and the flat folding constraint of the origami model. Three types of derivative structures based on water bomb origami are provided, and the target curved surface can be simulated in a more diversified mode. Secondly, a rigid paper folding movement process of paper folding is simulated by controlling a certain single variable. On the basis of researching a water bomb origami derivative structure modeling method, the degree of freedom of each vertex is considered, and the number of connecting rods around the vertexes is reduced, so that the degree of freedom of the vertexes is reduced. A favorable condition is added for the research of target curved surface fitting.

Description

Technical field [0001] The present invention relates to the field of computer origami in computer origami has a field of generally cylindrical properties, and in particular to the derived structure obtained by WaterBOMB-added rectangular blocks constituting the base origami unit, and simulates its rigid folding process. Background technique [0002] The rigid object is external for external force, and there is no change in shape, and the specific manifestation does not occur in stretching and deformation. From small brackets to large solar sails to the braking and promotion of the robot, the application of rigidity changes in people's lives is increasingly wide, while the origami structure can provide a modified template. Origami is an old origami art because it has a unique nature, such as expandability, flat folding. The application of origami structures in deformation is mainly to simulate the target surface by the origami structure. As inventive patent: a dielectric elastomer...
