为方便实现双曲扁网壳受力性能分析,应用APDL(Ansys parametric design language)参数化设计语言,研制5种双曲扁网壳结构参数化设计宏程序。并根据长短跨矢高、长短跨网格数以及支座形式的变化,选取5种双曲扁网壳结构的170种工况,进行结构受力性能比对分析。结果表明:5种类型双曲扁网壳中,三向格子型网壳结构受力性能最合理,长跨矢跨比为1/2、短跨矢跨比为1/6为宜。
In order to facilitate the analysis of the mechanical behavior of hyperbolic flat reticulated shell, five parametric design macro programs of hyperbolic flat-shell reticulated shell were developed by using APDL (Ansys parametric design language) parametric design language. According to the variation of length and length of cross-head, length and length of cross-grid and the form of support, 170 kinds of working conditions of five hyperbolic flat-shell reticulated shell structures were selected to analyze the mechanical performance of the structure. The results show that the three grids of five types of hyperbolic flat reticulated shells have the most reasonable mechanical properties, the long span spanwise span ratio is 1/2 and the short span span ratio is 1/6.
