Multi-gradient bionic corrugated sandwich plate-foam core anti-collision energy absorption device
The invention relates to the technical field of high-performance bionic structures, in particular to a multi-gradient bionic corrugated sandwich plate-foam core anti-collision energy absorption device. Comprising an external bionic corrugated sandwich plate, a built-in bionic corrugated framework and a foam core, and the external bionic corrugated sandwich plate and the built-in bionic corrugated framework have the structural characteristics of a multi-gradient triangular unit layer and are designed by taking a microstructure of a baretail mantis shrimp as an inspiration; the multi-gradient triangular units of the external bionic corrugated sandwich plate and the built-in bionic corrugated framework are arranged in a way that the internal microstructure of the crayfish of the bird tail mantis shrimp is taken as a bionic prototype, the triangular units are arranged in multiple layers, and the triangular units in different layers are arranged in a multi-gradient way, namely, the size of the triangular units in each layer is in a certain multiple relationship. And the foam core and the built-in bionic corrugated framework form a composite structure with relatively strong energy absorption and supporting effects.
本发明涉及高性能仿生结构技术领域，具体是一种多梯度仿生波纹夹层板‑泡沫芯防撞吸能装置。包括外置仿生波纹夹层板、内置仿生波纹骨架、泡沫芯，其外置仿生波纹夹层板和内置仿生波纹骨架是以赤尾螳螂虾微观结构为灵感而设计的具有多梯度三角单元层的结构特性，所述外置仿生波纹夹层板和内置仿生波纹骨架的多梯度三角形单元设置是以雀尾螳螂虾的虾螯内部微观结构为仿生原型，三角形单元为多层布置，且不同层的三角形单元为多梯度设置，即每层的三角形单元的尺寸呈现一定倍数关系。而泡沫芯与内置仿生波纹骨架组成了具有较强吸能和支撑作用的复合结构。
