| 目的 研究矿泉水瓶体凹槽结构形状的优化设计。方法 在有限元显式分析软件 LS-DYNA中，通过不同厚度分布的实常数，建立厚度可连续变化的瓶体壳模型。针对影响瓶体垂直载压能力的凹槽形状参数，包括凹槽内高度、深度以及拔模角度，设计正交试验。在正交试验的基础上，利用单因素试验优化外部拐角处的倒角半径。结果 通过正交试验的极差分析，确定凹槽内高度2 mm，槽深度1 mm，拔模角度2°为最优方案。在单因素试验的基础上，综合美学和生产方面的考虑，确定倒角半径1 mm为最优方案。结论 以矿泉水瓶体垂直载压能力所受影响最小为目标，得到了凹槽形状参数的最优组合方案，并为其他参数的优化提供了一种方法。 |

| The work aims to study the optimized design of the groove structure on the mineral water bottle. The bottle shell model of which the thickness continuously varied was established through the real constant with different thickness distribution by use of explicit dynamic software LS-DYNA. A orthogonal test was designed according to the shape parameters of the groove which influenced the top load capacity, including the internal height, depth and draft angle of the groove. The outside fillet radius was optimized using single-factor test based on the result of orthogonal test. The parameter combination of internal height of 2 mm, depth of 1 mm, draft angle of 20 was the optimal solution, which was got by the range analysis of orthogonal test. Fillet radius of 1 mm was the optimal solution which was got by single-factor test as well as considering the factors such as aesthetics and producing. In conclusion, the optimal shape parameters combination for the groove is obtained according to the lowest influences to the top load capacity of the mineral water bottle. It offers a way to optimize other parameters. |
