| 目的 通过拓扑优化和尺寸优化方法对周转铝箱进行轻量化设计，以解决结构强度设计过剩及多工况性能不均衡的问题。方法 利用Hyperworks软件对周转铝箱的堆垛工况、运输冲击工况、吊装工况进行有限元分析，对各工况分析结果进行评价。建立基于折衷规划法的多工况拓扑优化数学模型，通过Optistruct软件进行优化求解，获得最优载荷传递路径，并根据拓扑优化结果进行二次设计及有限元分析。最后将新结构的管材壁厚分为7个独立设计变量，通过尺寸优化方法进一步优化管材壁厚。结果 有限元分析结果表明基于经验设计的箱体结构安全余量较大，且各工况下的力学性能不够均衡。通过折衷规划拓扑优化设计了新的箱体结构，在同等壁厚下，箱体质量降低10.15%，且提高了横向刚度，使各工况的力学性能更加均衡。结论 根据折衷规划模型的拓扑优化方案，使周转铝箱在各工况下的性能得到协同优化，且轻量化设计后的箱体满足多种典型工况的使用要求，说明综合运用折衷规划拓扑优化和尺寸优化的方案是可行的，为金属包装箱的轻量化设计提供了理论依据。 |

| The work aims to carry out lightweight design to the turnover aluminum box through topology optimization and size optimization methods to solve the problems of excessive structural strength design and unbalanced performance under multiple working conditions. Hyperworks was used to carry out finite element analysis on the stacking conditions, transportation impact conditions and lifting conditions of the turnover aluminum box, and the analysis results under each working condition were evaluated. A multi-condition topology optimization mathematical model based on compromise programming method was established, and the optimal load transfer path was obtained through optimization and solution by Optistruct. According to the topology optimization results, the secondary design and finite element analysis were carried out. Finally, the wall thickness of the new structure was divided into seven independent design variables, and the wall thickness was further optimized by the dimensional optimization method. The results of finite element analysis showed that the safety margin of the box structure designed based on experience was large, and the mechanical properties were not balanced under various working conditions. A new box structure was designed by compromise programming and topology optimization methods. Under the same wall thickness, the mass of the box was reduced by 10.15%, and the lateral stiffness was improved, so that the mechanical properties under each working condition were more balanced. According to the topology optimization scheme of the compromise programming model, the performance of the turnover aluminum box under various working conditions is collaboratively optimized, and the lightweight design of the box meets the use requirements under a variety of typical working conditions, which shows that the comprehensive use of the topology optimization and size optimization scheme of the compromise programming is feasible, and provides a theoretical basis for the lightweight design of metal packaging box. |
