| 摘 要： | 为快速评估新型弹药中电子部件的储存可靠性,提出了使用步进应力加速退化试验（SSADT）的方法。首先给出了电子部件SSADT方案,接着提出了基于累积退化量的电子部件SSADT可靠性评估的基本假设,然后详细分析了基于累积退化量的电子部件SSADT可靠性评估思路和方法。该方法实现了＂零失效＂情况下弹药电子部件的储存可靠性评估。

| Abstract: | In order to assess the storage reliability of electronic parts of new ammunition quickly,the method of step-stress accelerated degradation testing（SSADT） was put forward.First the scheme of electronic parts by SSADT was expatiated.Then the basic hypothesis of reliability assessment of electronic parts based on cumulative degradation by SSADT was brought forward.The train of thought and method of the reliability assessment method was analyzed particularly.The method achieved storage reliability assessment of ammunition electronic parts under the condition of ＂zero failure＂. |
