Abstract

In order to assess the storage reliability of ammunition contained electronic components rapidly, the method of step-stress accelerated degradation testing (SSADT) is presented. First the scheme of SSADT and the train of thoughts of reliability assessment are expatiated. Then the basic hypotheses of reliability assessment of SSADT for ammunition based on pseudo-failure life are put forward. And the method of reliability assessment of SSADT for ammunition based on pseudo-failure life is analyzed particularly. Compared with accelerated life testing, the method of SSADT for ammunition can decrease testing time to a great extent while not increase the sample size, so it has a higher cost-effective ratio.
