The invention relates to a bionic water spider diving bell latticed shell structure based on SLM forming and a forming method of the bionic water spider diving bell latticed shell structure. The reticulated shell structure comprises a spherical reticulated shell with a large rise-span ratio and a base node seat used for supporting the spherical reticulated shell, the spherical reticulated shell is formed by a plurality of rod structures distributed on the spherical surface, and the included angle between any two adjacent rod structures is the same; the base node seat is of a circular ring structure with 12 nodes uniformly distributed in the circumferential direction, the spherical reticulated shell and the circular ring structure are cross-linked to the nodes, and the number of rod structures of the spherical reticulated shell cross-linked to the nodes is 1 or 2; the rod structure is a circular-section rod structure, and the section diameter/(vector height of the spherical reticulated shell) of the rod structure is 0.1-0.15; and the included angle is set to be larger than or equal to 60 degrees and smaller than 90 degrees. The latticed shell structure combines the characteristics of a truss structure and a thin shell structure, and has the advantages of being reasonable in stress, high in safety, good in economic performance, high in applicability, large in span and the like.

    本发明涉及一种基于SLM成形的仿生水蜘蛛潜水钟网壳结构及其成形方法。所述网壳结构包括:具有大矢跨比的球面网壳和用于支承所述球面网壳的基底节点座,所述球面网壳由分布在球面上的多个杆结构形成,任意相邻两个杆结构之间的夹角均相同;所述基底节点座为圆周方向均匀分布有12个节点的圆环结构,所述球面网壳与所述圆环结构交联于所述节点,且与所述节点交联的所述球面网壳的杆结构的数量为1或2个;所述杆结构为圆截面杆结构,杆结构截面直径/(球面网壳的矢高)为0.1~0.15;所述夹角设置为大于等于60°且小于90°。该网壳结构结合桁架结构和薄壳结构的特征,具有受力合理、安全性高、经济性能好,适用性强、跨度大等优点。
