| 中文摘要: |
| 对于结构复杂的新型弹药元件， 难以通过传统的统计试验方法来验证其可靠性， 而现阶段基于模型的加速寿命试验方法受到加速模型的限制， 只适应于元器件级及材料级的传统弹药元件。在明确某灵巧弹药红外敏感器部件结构特征的基础上， 以步进加速寿命试验理论与方法为依据， 逐一对各组件进行分层次的贮存失效分析， 归纳出贮存环境中导致红外敏感器部件失效的主要应力类型， 并提出该部件可采取恒定湿度、 步进温度的加速寿命试验方法进行可靠性验证。 |
| 英文摘要: |
| It is difficult to verify the reliability of a new type of ammunition components through traditional statistical testing methods. The model-based accelerated life test method limited by acceleration model, is applicable only to component and material level at present. Based on accelerated life test theories and methods, the structural characteristics of smart ammunition infrared sensor components were determined, and the hierarchical storage failure analysis were carried out one by one on each component. The main types of storage environment stress leading to component failure were summed up, and the point of view of applying step accelerated life test program was put forward. |
