Space single-layer latticed shell node positioning design method
The invention relates to a space single-layer latticed shell node positioning design method. The method comprises the steps that the number of rod pieces is obtained; determining a vector along the direction of the rod piece; determining a normal vector of a clamping surface between every two adjacent rod pieces; determining a positioning normal vector of the node; and completing positioning lofting of the nodes based on the positioning normal vectors of the nodes. Compared with the prior art, the method has the advantages that the azimuth vector of the rod piece connected with the node is determined, the normal vector of each plane defined by the adjacent rod pieces is found out, and then the normal vector for node positioning is obtained in a vector sum solving mode. Therefore, the lofting and positioning problems of the spatial reticulated shell nodes in actual production are solved, bending and twisting of steel plates generated by connecting the designed and positioned nodes and all the surrounding rod pieces are the most average, the generated total bending and twisting is the minimum, the node effect and manufacturing feasibility are guaranteed, and the production efficiency is improved. Mathematical basis can be provided for positioning of nodes of a spatial reticulated shell structure or under similar conditions, and batch and automation are achieved.
本发明涉及一种空间单层网壳节点定位设计方法，包括：获取杆件数量；确定顺杆件方向的向量；确定各相邻两杆件之间夹面的法向量；确定节点的定位法向量；基于节点的定位法向量，完成节点的定位放样。与现有技术相比，本发明通过确定与节点相连杆件的方位向量，并找出相邻杆件围成的各个平面的法向量，再通过求矢量和的方式得到节点定位的法向量。由此解决空间网壳节点在实际生产中的放样定位问题，所设计定位的节点与周围的每一根杆件连接所产生的钢板的弯扭最平均，且产生的总弯扭最小，保证了节点效果和制作的可行性，能够为空间网壳结构或类似情况下节点的定位提供数学依据，并以此实现批量化和自动化。
