Abstract:由于具备重量轻、能承受大变形、易于展开/折叠等优势,柔性薄膜结构适用于航空航天、电子通讯等重要工程。然而,薄膜抗弯刚度极小,几乎不能承受任何面内压缩应力,容易出现面外屈曲现象(即褶皱),严重其形面精度和结构性能。此外,制造过程中薄膜中的缺陷不可避免,可能对其性能产生影响。本文基于不确定性非概率有界场模型,采用级数展开方法和多椭球凸集来量化薄膜厚度初始缺陷,研究表明厚度不确定性对薄膜褶皱行为存在重要影响。进一步通过寻找最不利缺陷,评估考虑初始缺陷情况下薄膜褶皱的扰动范围。其次,基于主应力-主应变准则,分别建立以相对密度为设计变量的无皱化拓扑优化模型和以夹具形状为设计变量的夹具形状优化模型,实现薄膜结构无褶皱化。提出无皱化约束的正则化等效策略和可行域松弛方法,解决了优化模型求解过程中存在的灵敏度计算困难和可行域极端狭窄现象。数值算例和物理试验表明薄膜结构中考虑缺陷的必要性,并验证了本文模型和方法的有效性。
