白酒包装件跌落有限元分析与优化设计

目的基于产品的基本参数和流通环境,测试白酒包装件的缓冲性能,并对其加以改进和优化。方法通过Pro/E软件建立白酒瓶和白酒包装件模型,在不同跌落方式和跌落高度下采用Ansys/LS-DYNA软件对其进行跌落仿真模拟实验。结果得到了白酒和整体包装件在跌落冲击过程的应力-应变变化规律。结论白酒瓶最易损坏部位分别在瓶肩和瓶身连接部位及瓶身和瓶底连接部位,并对酒瓶、衬垫、包装件进行了优化设计。

Finite Element Analysis of Wine Bottle Drop and Optimal Design

Objective To obtain the cushioning property of wine package based on the parameters and circulation environment of the product, and then improve and optimize it. Methods Models of wine bottle and wine package were established by Pro/E, in both cases, drop impact simulation comparative analyses of different way and drop height were conducted by software of Ansys/LS-DYNA. Results The changing rule of stress-strain about the wine bottle and the whole package in the process of impact was obtained. Conclusion The most easily damaged places of wine bottle were the shoulder and bottom as revealed by the simulation experiment. Optimal design of wine bottle, cushion and package was accomplished.
