| 摘 要： | 以短程线网壳的总质量为目标函数,以网壳的网格数、矢高、杆件截面面积和节点体积作为优化设计变量,采用一维搜索法与相对差商法相结合的序列两级优化方法进行截面优化设计。对不同跨度、不同矢跨比和不同网格划分密度的多个单层短程线球面网壳结构进行了计算,用回归分析法得出网壳最优网格划分数量、矢跨比、杆件截面面积和节点体积。

| Abstract: | The total weight of short-line shell has been taken as objective function,the number of grid shell,vector high,bar-sectional area and volume have been taken as the design variables node and uses cross-section level optimization which combines one-dimensional search method and the relative difference quotient sequence to optimize cross-section.Different spans and different span ratio and the number of different mesh density single short line of spherical shell structure are calculated and regression analysis... |
