Title:
SPACIAL CURVED SURFACE BRAIDED STRUCTURE SYSTEM FOR MULTI-LAYER SELF-MOLDING ELASTIC RODS AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/037070
Kind Code:
A1
Abstract:
A spacial curved surface braided structure system for multi-layer self-molding elastic rods and a construction method therefor. The structure system comprises a skeleton structure of the spacial curved surface, and the skeleton structure is an up-and-down overlapping or inside-and-outside overlapping grid skeleton with more than two layers. Each grid skeleton is a set of continuous and flexible elastic rod pieces, and the elastic rod pieces are braided and interspersed by bending the rod pieces and form a self-molding grid skeleton by connecting each connection point between the rod pieces. The connection points are in hinge connection or rigid connection. The grid skeleton comprises a first layer of rod pieces at a lower layer or an inner layer and a second layer of rod pieces at an upper layer or an outer layer, and the second layer of rod pieces are overlapped at the normal direction on the upside or at the outside of the first layer of rod pieces. The present invention innovatively adopts a structure form with better mechanical properties, and can be applied to complex spacial curved surface structures having complicated topological relations and diversified morphological changes, thereby solving the technical problems of construction difficult in existing complex spacial curved surface structure systems and low controllability in realizing curved surface forms.
