| 摘 要： | 研究汽轮机缸体建模的一般方法，基于ＡｕｔｏＣＡＤ和有限元建模工具ＶｉｚｉＣａｄ，提出了汽轮机缸体建模的一种新思路。根据缸体结构的特点，将缸体分成若干子模块，实施有限元网络自动剖分，得到了模块的有限元模型，再进行子模块粘接，建立整个缸体结构的有限元模型。应用此方法，得到了国产１２５ＭＷ汽轮机低压内缸三维有限元整体模型。

| Abstract: | This paper deals with the general method to construct a model of the turbine casing in 3 dimension FEM. On the base of AutoCAD and ViziCad tools, we suggested a new idea to construct the meshes of the turbine casing. The while casing is divided into a series of sub - model, and the mesh of this sub - model is obtained by automatic mesh generation. The meshes of the while casing are obtained by the adding of the submodel one by one. As an example, the meshes of a turbine casing are shown in the paper. |
