【摘要】 针对现有文献中对球面网壳优化变量的选取大多限于截面积的不足,提出以网壳曲率半径、网格尺寸(包括每层网壳的节点数和网壳的层数)、杆件截面积(包括杆件直径以及壁厚)为变量的综合优化设计方案.以施威德勒型(Schwedler)球面网壳为例进行优化,结果表明综合优化设计方案效果显著.更多还原

【Abstract】 In the light of the imperfections of the selection of the Reticulated shell optimization variants only limited to the sections in the present documents,this paper proposes comprehensive optimization design including the shelly radius、net size(the shelly nodes number and the layers number),the diameter and thickness of steel tube,taking Schwedler Reticulated Shell as an example.The results of optimization indicate that it is remarkable.更多还原
