Abstract

本发明提供了一种复合材料压力容器纤维缠绕角敏感度分析与优化方法，属于复合材料压力容器设计制造的技术领域，该方法包括S1，模型分区；S2，制造约束；S3，建立本构关系；S4，设计变量参数化；S5，优化问题的数学表述；S6，灵敏度分析求解；S7，设计变量更新；S8，迭代循环与收敛判定。本方法将优化问题的设计变量从不可制造的“局部铺层角”转换为决定纤维空间角的实际“缠绕路径参数”，从而在优化过程中严格嵌入制造约束，通过构建高保真有限元模型并采用高效的解析灵敏度分析，实现设计空间的高效探索，最终输出与数控缠绕设备无缝衔接的、可直接用于多束无交叉生产的缠绕角分布方案，实现从优化设计到制造规划的技术闭环。
