网格形状为等边三角形柱面网壳的研究

The study on the shape of an equilateral triangle mesh cylinder shell

提出等边三角型柱面网壳的假设,根据网壳结构的几何特性,推导其网格形状为等边三角形时的条件公式,然后利用ANSYS的参数化编程语言APDL,编制相应的宏程序,实现其参数化建模。最后结合算例进行静定分析,与五种基本型式柱面网壳的静定分析结果比较,验证其假设的合理性。

Make an assumption on equilateral triangular cylindrical shell,according to an equilateral triangular structure of the cylindrical shell geometry,deduced the condition formula on shape of an equilateral triangle grid,and Then comes the use of ANSYS parametric programming language APDL,preparation of the corresponding macro program,to achieve its parametric building mode.Finally,with examples of equilateral triangular cylindrical shell analysis for statically indeterminate,and verify the reasonableness of the assumptions compared to five basic types of cylindrical shell of indeterminate results.
