 连续体结构的拓扑优化相对其尺寸优化、形状优化是较高层次的优化,由于其数学模型难以描述,所以被认为是当前结构拓扑优化领域中挑战性的课题。
  《屈曲约束的拓扑优化(英文版)》利用ICM(independent、continuous、mapping,即独立、连续、映射)拓扑优化方法,对连续体考虑屈曲的拓扑优化问题进行了研究,建立了以结构的质量小为目标,以屈曲临界力为约束以及与位移、应力组合为多约束的四种拓扑优化模型,将优化模型转化为对偶规划,并利用序列二次规划求解,减少了设计变量的数目,缩小了模型的求解规模,并基于MSC.Patran/Nastran软件平台,利用其二次开发语言PCI,实现了全部拓扑优化程序的编制。 [1]
