초록
目的 减轻 LNG薄膜罐主容器的总质量,从而促进液化天然气存储设施的发展及市场拓展. 方法 对薄膜罐主容器的 基本几何参数进行了设计,并建立了储罐数学模型和需要的目标函数;分析计算了储罐在满罐状态下的受力情况,利用 ANSYS软 件对基础几何数据进行了参 数 化 设 置 和 罐 壁 厚 度 优 化;利 用 粒 子 群 算 法 及 MATLAB 软 件 编 程 对 此 穹 顶 数 学 模 型 进 行 求 解. 结果 穹顶最优曲率半径为28000mm,罐壁最小厚度减小了0.50mm,罐顶总质量减少了103t,罐壁最大厚度减小了0.62mm. 结论 经气压试验后优化计算结果合格,对 LNG薄膜罐的轻量化研究及降低成本具有重要的参考价值.
