大口径舰炮弹药储供系统运用中心伺服扬弹、推送对中及箱式补给等新技术之后，可靠性相比现役舰炮所用技术有了显著的改善。根据其故障模式构建全组成参与的非正常扬弹故障树，在此基础上依托底事件进行可靠性分配研究。基于分配结果给出储供系统可靠性提升策略，同时也对可靠性评估有一定的工程意义。结果表明链条或齿轮箱故障、活门组件失效以及回转模块故障等事件为系统的薄弱环节，在设计过程中应着重分析其故障原因，以及由于高任务可靠度等原因对此类底事件分配较小的可靠性指标。
After the large-caliber naval gun ammunition storage and supply system uses new technologies such as central servo lift, push centering and box replenishment, the reliability has been significantly improved compared with the technology used in active naval guns. Then constructs a fault tree for abnormal bombing with full participation according to its failure mode, the reliability distribution research is carried out. The reliability improvement strategy of the storage and supply system is given, has a certain significance for the reliability evaluation. The results show that events such as chain or gearbox failure, valve component failure, and rotation module failure are the weak links of the system. During the design, the reasons for the failure should be analyzed and the allocation of such bottom events due to high task reliability and other reasons should be small. The reliability index.
