| 摘 要： | 针对影响星载铷原子频标可靠性的环境因素进行了分析,确定了影响星载铷原子频标可靠性的主要环境敏感应力,根据可靠性强化试验理论和星载铷原子频标的技术特点,设计了可靠性强化试验方案。依据此方案对新研制的某型星载铷原子频标工程样机实施了可靠性强化试验。试验结果表明,该方案对确定该型号铷原子频标样机工作极限、激发其潜在缺陷,均有较好的效果,从而为实现星载铷原子频标的可靠性增长提供了新的思路。同时本研究对同类高可靠航天产品的可靠性增长可提供借鉴。

| Abstract: | The Spaceborne Atomic Frequency Standarda(AFS) play a critical role in many space systems,their performance and reliability will influence functions of these systems.In this paper,the various environmental factors which affect performances and reliability of Spaceborne Rubidium AFSs firstly were analyzed,and the main environmental sensitivity stresses were confirmed,secondly the reliability enhancement test plan which was based on the theory of reliability enhancement test and technical characteristics of the Spaceborne Rubidium AFSs was designed,finally a reliability enhancement test on certain Spaceborne Rubidium AFS EM was implemented.The test result indicates that the test plan has preferable effects on confirming the operational limits of this Spaceborne Rubidium AFS and exploding its latent flaws.It provides a new method which may impuove reliability of Spaceborne Rubidium AFSs. |
