【摘要】：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。
[Abstract]:Objective to study the optimum design of the groove structure of mineral water bottle. Methods in the finite element explicit analysis software LS-DYNA, the real constant of different thickness distribution was obtained. To establish a continuous thickness of the bottle shell model. For the vertical load capacity of the bottle groove shape parameters, including the groove height, depth and drawing angle, the design of orthogonal test. On the basis of orthogonal test. The chamfer radius of the external corner was optimized by single factor test. Results the height and depth of the grooves were determined to be 2 mm and 1 mm by means of the range analysis of orthogonal test. Drawing angle 2 掳is the optimal scheme. On the basis of single factor test, the aesthetic and production considerations are synthetically considered. 1 mm radius of chamfer is determined as the optimal scheme. Conclusion the optimal combination scheme of groove shape parameters is obtained with the aim of minimizing the influence of vertical load capacity of mineral water bottle. It also provides a method for optimization of other parameters.

【正文快照】： 垂直载压能力是矿泉水瓶设计和生产中一项重要的评价指标,在QB 2357—1998聚酯(PET)无汽饮料瓶中明确规定,无汽饮料瓶的垂直载压能力要大于等于100 N[1]。为了提高瓶子的抓握性能和瓶体周向的抗挤压能力,往往在瓶体上设计一些凹槽结构,但这种结构会降低瓶体的垂直载压能力[2]
