目的 研究设计结构合理、 可靠性高和方便弹药取放的弹药储运方舱内部结构。方法 以我军某口径系列的炮弹为对象， 以弹药储运方舱的技术条件、 要求为依据， 针对弹药的特点， 分析了弹丸、 药筒和引信的放置方式， 并设计了6种内部结构设计方案。结果 经过分析比较， 方案1和方案4的舱体强度是最强的， 方案4固定装置的可靠性、 取放弹药的方便性优于其他方案。结论 方案4的方舱结构合理， 可靠性高， 方便使用。

To design ammunition storage and transportation shelter internal structure with the characteristics of rational structure, high reliability and convenient take put. The article analyzed the placement of pill, cartridge case and fuze, and designed 6 schemes of internal structure design, using the howitzer projectile with a ceatain diameter as the study object, and based on the technology requirement and demand of the ammunition storage and transportation shelter as well as the ammunition characteristics. By comparing and analyzing, it was found that the strength of shelter schemes 1 and 4 was the best, while scheme 4 was better than the other schemes in reliability of fixed device and convenience of taking and putting ammunition. Scheme 4 had the characteristics of rational structure, high reliability and convenient use for force.
