| 摘 要： | 文中介绍一种新的空间板系结构优化方法及相应的程序系统SPO。该方法不依赖一维搜索确定步长。用四边形等参元和四边形拟协调元经组合后对空间板系结构进行有限元分析。在优化计算中采用适当的性态敏度分析方法可使结构重分析次数大大降低。

| Abstract: | A programming system (SPO) for the structural optimization of space plates structure is presented. The optimization part of the system does not rely on one dimensional search to compute a step size at any design iteration. The finite element analysis part of the system employed fournode quadrilateral isoparametic element and quasi-conforming four-node quadrilateral MINDLIN element, and by combining the two elements, the spaceplates structure is analysed. To cooperate the optimization part and sensitivity analysis part of the system, the number of structure re-analysis is only one at any design iteration. |
