混沌优化法在双层圆柱面网壳结构优化中的应用

Application of chaos optimization algorithm in the optimization of double-layer cylindrical latticed shell

将混沌优化方法引入双层圆柱面网壳结构的优化设计中 ,实现了对网格尺寸、结构厚度、矢跨比作为连续变量的同步优化 ,编制了相应的程序 .大量算例证明了该法优化网壳结构的高效性 ,且人为工作量小、精度高 .

It was proposed firstly in this paper that chaos optimization algorithm could be used in the optimization design of double layer cylindrical reticulated shell,which realized the synchronous optimization of the rise/span ratio, grid size and the vault thickness as continuous variables. Through compiling programs and analyzing samples the high efficiency and precision of this method have been proved, and more excellent geometrical parameters of double layer cylindrical reticulated shell have been gotten with different span than which get form traditional method.
