Design method of porous spiral layered bionic structure

The invention is suitable for the technical field of spiral layered structures, and provides a porous spiral layered bionic structure design method which comprises the following steps: starting from the characteristics of a spiral layered structure of mantis shrimp attaching foot shells and a polycellular thin-wall structure of gulfweed rhizomes; main structural elements and structural mechanisms are extracted through similarity analysis and extraction of the spiral layered structure of the mantis shrimp shell and the multi-cell thin-wall structure of the gulfweed rhizome, and structural feature extraction and fusion are performed according to the characteristics of the spiral layered structure of the mantis shrimp shell and the multi-cell thin-wall structure of the gulfweed rhizome. According to the method, a three-dimensional macroscopic preliminary porous spiral layered bionic structure is established, the range of each element and the size of each element is determined and used for structural construction
