Novel fabricated cast steel joint of grid structure
The invention relates to a novel fabricated cast steel joint, and belongs to the field of innovation of space grid structure joints. The interior of a novel fabricated cast steel ball joint is a cavity. External branch pipes and a steel ball are connected into a whole. The connection between the branch pipes and the steel ball enables the structure to be smooth through fillets. The branch pipes are distributed in the circumferential direction of the steel ball. Four steel pipes of the upper hemisphere obliquely extend outwards, and four steel pipes of the middle hemisphere extend outwards in the axial direction. The middles of the connecting parts between the steel pipes and the steel ball are hollow. Oblique rod pieces in the ball are obtained through topological optimization and is integrated with the outer ball shell. A steel ball surface is provided with a curved surface shape which is obtained by topological optimization calculation by taking the number, the positions and the diameters of the branch pipes as parameters and is matched with the stress of borne steel rods. Topological optimization analysis is carried out on the ball joint, so that the self-weight of the fabricated cast steel ball joint is greatly reduced while various mechanical properties are met.
本发明涉及一种新型装配式铸钢节点，属于空间网格结构节点创新领域。新型装配式铸钢球节点内部为空腔，外接分管与钢球连接为一个整体，分管与钢球之间的连接通过倒圆角使得结构光滑，分管沿钢球的周向分布，上半球四根钢管斜向外伸，中半球四根钢管沿轴向向外伸，且钢管与钢球之间的连接部分中间为空心，球内部斜向杆件由拓扑优化得到，与外部球壳为一个整体。钢球表面具有以分管数量、分管位置、分管直径为参数的经拓扑优化计算得出的与所承载钢杆受力相匹配的曲面形状。对球节点进行拓扑优化分析，使装配式铸钢球节点在满足各项力学性能的同时极大减轻了自重。
