摘要
给出了简支预应力 U型薄壳渡槽槽身整体结构优化设计的数学模型 ,推导了位移灵敏度和应力灵敏度的表达式。编制了以有限元程序 ADINA为结构分析求解器的结构优化设计通用程序 ,并对简支预应力 U型薄壳渡槽进行了槽身整体结构优化设计。结果显示本文方法是有效的。
The mathematical model of the global optimization for prestressed U-thin-shell aqueduct structure with simple supports is put forward.The expressiones of displacement and stress sensitivity are derived.The general porgram of the structure optimization based on structural analysis solver-FEM program ANINA is designed,and the aqueduct body of prestressed U-Thin-Shell with simple supports is designed by means of the program.The result indicates that this method is effective.
