摘要:
为了评估起爆电容的贮存可靠性,采用了竞争失效模型,模型利用了失效数据,将试验过程中的退化数据也考虑在内。在突发失效和退化失效相关性分析中,采用随机抽样的方式避免失效时间分配产生的偶然误差,得到的结果更加客观、真实。以某起爆电容恒定应力加速寿命试验数据为例,验证了模型的有效性。
Abstract:
To evaluate the storage reliability of initiating capacitor which is the vulnerable component of fuze in weapon system,a competing failure model is used considering both the degradation data and failure life.The random sampling is adopted to avoid accidental error,which is caused by distributing failure time artificially in the analysis of pertinence between catastrophic failure time and degradation,and a more precise and objective result is obtained.An example of initiating capacitor with competing failure data in constant stress accelerating test is applied to validate the proposed method.
