摘要:为研究适合云爆战斗部10a存储条件的密封接口结构，针对不同材料不同结构密封圈的密封接口，在内压力0.6MPa条件下进行了密封性测试。密封实验结果表明：使用矩形截面聚四氟乙烯密封圈可以实现密封圈与零件完全贴合；选择密封圈既要考虑材料具有恰当的弹性模量，还要考虑密封圈在内压力作用下，与零件贴合更紧密而非脱离。本研究可为云爆战斗部密封设计提供参考。
Abstract:To design the sealing interface structure suitable for ten-year storage condition of cloud explosive warhead, through comparing the sealing performance of sealing interface with different materials and different structures under 0.6MPa internal pressure, the rectangular section teflon sealing ring was determined, to meet the sealing performance requirement under the condition of internal pressure. The seal design is needed to achieve a complete fit between the sealing ring and the parts, and is necessary to consider that the material has appropriate elastic modulus. This conclusion could provide a reference for the seal design of the warhead.
