摘　　要：针对引信元件在故障模式下可能会出现作用失效的问题,利用理论与实际数据相结合的方法,完成故障模式影响及危害性分析(FMECA)。首先对引信元件进行故障模式及影响分析(FMEA),然后采用基于层次分析法(AHP)赋权的模糊综合评价模型完成危害度分析(CA)。分析结果表明,在FMEA定性分析中,延期药柱缺陷引起的引信瞎火是发生频率最高的故障,雷管缺陷对引信可靠发火的影响最大。在CA定量分析中,电池、雷管、自毁弹簧故障的危害度等级较高。因此,在引信的设计过程中,应重点关注电池、雷管、自毁弹簧相关设计指标是否达到设计标准,确保引信可以可靠工作。In order to solve the problem that the fuze element may have action failure in fault mode,effects and criticality analysis was completed by combining theory and practical data.Failure model and effects analysis of fuze components was carried out,and then criticality analysis was completed by fuzzy comprehensive evaluation method based on AHP.The analysis results showed that in the FMEA qualitative analysis,the fuze blind fire caused by the delay charge column defect was the most frequent fault,and the detonator defect had the greatest influence on the reliable ignition of the fuze.In CA quantitative analysis,the hazard level of battery,detonator and self-destruct spring failure was higher.Therefore,the design of indicators related to battery,detonator and self-destruct spring meet the design standards should be paid more attention to ensure the fuze reliably.
