| 目的 分析影响弹上设备湿热试验典型外观不合格的原因及失效机理，给出弹上设备适应湿热大气的相关建议。方法 给出某型号湿热鉴定试验过程中，弹上设备出现的三种典型外观不合格现象——漆层起泡、螺钉锈蚀和电连接器锈蚀。通过建立与漆层起泡、螺钉锈蚀和电连接器锈蚀不合格现象相对应的故障树，分析3种典型外观不合格的失效原因，并得到相应的失效机理。结果 总结了弹上设备湿热试验后外观发生不合格的原因，并从设计、选材、介质隔离角度给出了弹上设备适应湿热大气的相关建议。结论 为提高弹上设备耐湿热环境的能力，进而提高装备的贮存可靠性，使其能够从贮存状态直接转入能使用状态，从而提高其贮存可靠性、战备完好性和系统效能提供了指导。 |
| 英文摘要: |
| To analyze the reasons and failure mechanisms that affect the typical unqualified appearance of the equipment on missile caused by the damp heat test and provide relevant suggestions for the missile equipment to adapt to the heat and humid atmosphere. Three typical unqualified appearances of the equipment on a certain missile caused by the damp heat test are given, namely blistering of paint, corrosion of screws and corrosion of electrical connectors. By establishing fault trees corresponding to the phenomenon of paint blistering, screw corrosion and electrical connector corrosion failures, the failure causes of three typical unqualified appearances are analyzed, and the corresponding failure mechanism is obtained. The reasons of the unqualified appearance of the missile equipment caused by the damp heat test are summarized. Relevant suggestions for the missile equipment to adapt to the heat and humid atmosphere from the perspective of design, material selection and media isolation are provided. It provides guidance for improving the ability of equipment on missile to withstand heat and humidity, and thus improving the storage reliability of the equipment, so that it can be directly transferred from storage state to usable state, thereby improving its storage reliability, operational readiness and system effectiveness. |
