Support joint of cable dome structure and machining method
The invention discloses a support joint of a cable dome structure and a machining method. The machining method comprises the steps of using three-dimensional mechanical design software for modeling an original node model, and obtaining a first file; importing the first file into finite element analysis software for topological optimization, and finally performing facet repairing and merging on a topological optimization result to obtain a second file with the topological optimization result; importing the second file into instant simulation software to carry out rapid smoothing processing on an optimization result; manufacturing the outer contour of the joint by using an evanescent mode, and filling and leveling up the hole characteristics in the joint model to obtain a foam model; brushing the foam model with an alcohol-based coating, and filling the foam model with organic ester sodium silicate sand to make a sand mold; and destroying the foam model and gasifying to form a cavity, inputting the mold core into the cavity, and performing mold closing and pouring after coating is brushed. According to the support joint manufactured through the machining method, the dead weight of the joint is reduced, and the safety and stability of the joint are improved; meanwhile, the support joint is clear in force transmission route and reasonable in stress form.
本发明公开了一种索穹顶结构的支座节点及加工方法，包括：使用三维机械设计软件对原始节点模型进行建模并获得第一文件；将第一文件导入有限元分析软件中进行拓扑优化，最后将拓扑优化结果进行刻面修复与合并，得到具有拓扑优化结果的第二文件；将第二文件导入到即时仿真软件中对优化结果进行快速光顺化处理；使用消失模制作节点的外部轮廓，填平节点模型中的孔特征，得到泡沫模型；将泡沫模型涂刷醇基涂料，填入有机酯水玻璃砂造砂型；将泡沫模型破坏气化形成空腔，将型芯下入，涂刷涂料后合箱浇注。采用该加工方法制作的支座节点，减小了节点的自重，提高了节点的安全性与稳定性；同时，该支座节点传力路线明确，受力形式合理。
