| 摘 要： | 铸钢节点作为一种新型的节点形式，目前已经广泛应用于大跨空间结构中。由于节点本身造型的复杂性，其计算必须借助于有限元软件进行分析。对于较重要的工程及受力较为复杂的铸钢节点，还需要通过一定的试验来验证有限元建模的准确性。运用大型通用有限元软件ANSYS对中国航海博物馆支座45°轴承组合支座铸钢节点进行真实工作状态的模拟和分析，同时考虑材料、接触非线性，并通过试验进行验证，说明模型建立正确且与试验吻合较好，从而为工程设计、分析提供参考。

| Abstract: | As one of the newest joint types,the cast-steel joints are utilized w idely in the long-span space structures. The analysis of the cast-steel joint must be processed by some finite element s oftware because the shape of the joint is very complex. By finite element a nalysis software ANSYS, the cast-steel joints for 45 degree bearing composite support of the China Sailing Museum in Shanghai are simulated and analyzed particularly, the material nonlinearity and contact nonlinearity are considered, and experim... |
