The Theoretical and Experimental Research on Accelerated Life Test of Collapsible Fabric Tank Storage Life Based on Reliability

Abstract:

Collapsible fabric tank which is an important part of oil equipment equips army with large reserves. The evaluation of collapsible fabric tank storage life, lacking of corresponding test data support, is on the conservative side, which causes manage and storage uncertainty to army. Based on reliability theory, storage life evaluation method of collapsible fabric tank is established. Failure data of collapsible fabric tank under several accelerated stress levels is obtained. According to probability distribution hypothesis test, Weibull distribution has better goodness of fit and life prediction model is obtained. A new maximum likelihood estimation is proposed as statistical analysis method and model parameters are evaluated. Storage life and reliability index of collapsible fabric tank under normal storage temperature are evaluated which brings collapsible fabric tank storage life potential into play and improves use economy.
