摘 要
由于玻璃材料的易碎性，因此玻璃在包装领域的应用是比较稀少的，而对于啤酒却出于种种原因不得不使用这种材料。在啤酒的储运过程中，瓶子的跌落和碰撞是造成包装损坏，进而造成内装物——啤酒泄露和损耗的一个重要原因。这种损耗所造成的损失往往巨大的，液体饮料不像其他商品，一旦泄露将是无法挽回的，况且还要追加上包装材料的损失。在啤酒饮用的高峰期夏天还经常发生因为酒瓶炸裂而产生的伤人事件。因此如何最优设计玻璃包装容器的防护包装，避免一些不必要的损失，也就成了一个值得研究的重要课题。
本文采用有限元分析软件ANSYS/LS-DYNA的跌落模块（Drop Test Module），它是进行模拟啤酒瓶跌落过程的应力变化的一个很好的软件。它基本的思路是，先是在软件上建立一个啤酒瓶的模型，定义材料的各种属性，进行网格的划分，形成有限元模型，然后设定瓶子的跌落初速度，重力加速度等参数，模拟缓冲包装系统的跌落响应试验。经过计算机的自动分析，就能够得到瓶子在整个跌落过程中的应力应变云图，和加速度响应动态特性，获取相关数据，最后优化啤酒瓶的缓冲包装结构设计。

Abstract
Because of the fragile of glass materials, glass packaging in the field of application in the package is relatively scarce, and for beer but for various reasons to use such materials. In the process of storage and transportation of beer, bottles of drops and packing collision damage is caused, thereby causing the contents - and the loss of beer leaked an important reason. This loss is often caused by the loss of huge, liquid beverage unlike other commodities, once the leak will be irreparable, plus packaging materials Besides the loss. Thus the protective glass containers packed optimal design will become an important topic worthy of study.
The drop module (Drop Test Module) of the FEM software ANSYS / LS-DYNA, is a good software to simulate drop test. Now here is Its basic idea, first in software on the establishment of a beer bottle model, the definition of the various attributes of a grid, a finite element model, and then set the bottle fell early speed, acceleration of gravity, and other parameters, simulation Buffer packaging system response to the drop test. After the computer's automatic analysis, we can get the whole bottle in the process of falling in the cloud of stress and strain, and acceleration of dynamic response, access to relevant data, the final optimization of the buffer beer bottle packaging structural design.
