摘　　要：鱼雷环境应力与工作应力的耦合效应直接影响其可靠性、工作寿命乃至作战效能。而耦合效应的研究尚处于起步阶段,对耦合效应下的失效模式和影响尚无系统研究。针对此,文章通过历史数据分析和典型失效案例介绍,系统总结了鱼雷常用零部件包括弹簧、紧固件、焊接件、轴类零件、轴承类、齿轮类、转子叶片类、液压系统和高分子材料类等,在环境应力和工作应力耦合下的失效模式,产生的失效模式包括松脱断裂、密封失效、腐蚀锈蚀和机械变形等,并分析了上述失效模式对鱼雷的影响。研究结果发现:鱼雷同时承受环境应力和工作应力的耦合作用,环境应力作为外界应力对鱼雷各零部件产生一定影响,使零部件缺陷或薄弱部位进一步恶化,同时工作应力进一步加深缺陷和薄弱环节的裂纹、磨损、老化的扩展,最终导致失效或故障。可为鱼雷可靠性分析和改进提供理论支撑。The coupling effect of environmental stress and working stress directly affects the reliability,working life,andoperational effectiveness of torpedo equipment.The research on the coupling effect for torpedoes is still in its infancy,and nosystematic research has been conducted on the failure mode and influence resulting from the coupling effect.Accordingly,thisstudy considered typical failure cases by analyzing historical data.The failure modes of key parts of the torpedo under thecoupling of environmental stress and working stress,including the spring,fastener,welded part,shaft part,bearing,gear,rotorblade,hydraulic system,and polymer material,were systematically summarized.The failure modes include loosening fracture,seal failure,corrosion,and mechanical deformation.We also explored the effects of these failure modes on the torpedo.Theresults show that the torpedo is subjected to the simultaneous coupling of environmental stress and working stress.Environmental stress,as an external stress,has a certain effect on the components of the torpedo,causing defects or weak partsof the components to deteriorate further,whereas working stress further deepens the cracks,wear,and aging of defects andweak links,ultimately leading to failure or malfunction.
