目的：研究某型末制导炮弹控制舱贮存加速寿命试验应力类型。方法在明确某型末制导炮弹控制舱结构特征的基础上，逐一对各部组件进行失效模式及失效机理分析，归纳出影响控制舱失效的主要应力类型。结果影响末制导炮弹控制舱贮存可靠度的主要环境应力是温度和湿度。结论选取温度做单应力加速寿命试验。%Objective To study the type of accelerated storage life testing stress of control-capsule of terminally guided pro-jectile.Methods Based on determining the structural characteristics of terminally guided projectile control-capsule, the failure mode and mechanism were analyzed one by one on each component. And main stress types that influenced control-capsule fail-ure were summarized.Results The main types of storage environment stress leading to component failure were temperature and humidity.Conclusion Temperature is applied for single stress accelerated life test.
