目的 提出一种适合各种炮弹的塑料包装结构设计方法。方法 针对不同炮弹对包装的不同要求，提出“内包装＋缓冲包装＋外包装”和“缓冲包装＋外包装”这2种总体包装结构形式，对内包装和缓冲包装结构设计方法进行归纳和总结，对外包装功能结构设计方法进行阐述，并对包装结构设计的其他细节进行说明。结果 文中提出的总体包装、内包装、缓冲包装和外包装等结构设计方法，适用于所有炮弹用塑料包装结构设计。结论 文中提出的炮弹用塑料包装结构设计方法行之有效，可为今后炮弹用塑料包装设计人员提供借鉴。

The work aims to propose a design method of plastic packaging structure suitable for all kinds of shells. Aiming at the different requirements of different shells, two kinds of overall packaging structures of "inner packaging + cushioning packaging + outer packaging" and "cushioning packaging + outer packaging" were put forward. The design methods of inner packaging and cushioning packaging structures were concluded and summarized. The outer packaging functional structure design method was described in detail, and other details of the design of the packaging structure were described. The design methods of general packaging, inner packaging, cushioning packaging and outer packaging and other structures were presented herein, which were applicable to the structure design of plastic packaging for all shells. The design methods of the plastic packaging structure for shells proposed herein are effective and can provide reference for the personnel who design plastic packaging for shells in the future.
