| Objective To study key factors and the main designing process of the accelerated storage life testing. Methods Based on the application achievement about the accelerated life testing in the development of missile, the theory of the accelerated life testing was analyzed, the key factors and the main designing process of test designing were presented, and the accelerated storage life testing based on constant stress was designed to estimate the storage life of the engine nozzle, which was focused on the primary vulnerable spots of the missile storage. Results The efficiency and precision of the accelerated storage life testing depended on the reasonable determination of vulnerable spots of storage, models of the accelerated testing, levels of accelerated stresses and test cycles, which were the dominate contents of test design. Conclusion Through case application study, the basic principles and processes proposed in this paper could provide effective guidance for establishment of the accelerated storage life testing program. |
