| Abstract: |
| 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. |
