initiating capacitor catastrophic failure degradation failure competing failure reliability assessment
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.
