| 摘 要： | 短程线型球面网壳的杆长和杆件的夹角最为均匀，杆件受力合理。根据等弧均分法，分析了短程线型球面网壳的几何特性，将直角坐标与球面坐标相结合，利用ANSYS的二次开发技术建立了一种短程线型球面网壳结构的建模方法，编制了相应的宏程序，实现了其参数化建模。该方法具有简单、快捷的优点，用户仅需输入矢高、跨度、扇形个数和频数这些控制参数即可自动生成所需模型，为下一步优化设计和后处理奠定了良好的基础。

| Abstract: | Geodesic reticulated shell is characterized by even length,symmetric angle of bars and well distribution of stress.Based on the theory of average arc,the geometry characteristics of geodesic spherical reticulated shells is studied,and a method of modeling geodesic spherical reticulated shells is put forward by combining orthogonal coordinate with spherical coordinate.The method applies ANSYS redevelopment techniques to program corresponding macro,and fulfils the speedy parametric modeling of geodesic spherical reticulated shells.The method has the advantages of simplicity and celerity and the model is created automatically after imputing several parameters,such as rise,span,cycle number and nodal circle number.It may be a part of preliminary process for optimal design and post process. |
