预应力U型薄壁结构整体结构优化
Global optimization for prestressed U-thin-shell structure
【摘要】 以线性和非线性有限元分析程序系统ADINA为结构分析求解器,以约束变尺度法和序列二次规划算法为优化算法,运用高精度的解析灵敏度算法,编制了结构优化设计通用程序SOPSA,并对水利水电工程中预应力U型薄壁结构进行了整体结构优化设计分析与计算,结果显示此方法是有效的.
【Abstract】 The mathematical model of optimizing prestressed U-thin-shell structure is used to derive the expressions of displacement and stress sensitivities. A general program of structure optimization is adopted,based on the FEM program ADINA as the structural analysis solver to develop the designs for the global optimization of a presstressed U-thin-shell structure.
