基于导弹现场数据的可靠性评估

通过检测可以有效监控导弹的状态，但是无法预知导弹出现故障的时间。为评估导弹贮存可靠性，需要对检测数据进行合理使用。但是目前利用导弹现场检测数据不够充分，造成导弹“检测过剩”或者“检测不足”的问题。通过研究导弹部件检测类型，总结导弹部件贮存情形，提出了4种导弹现场检测数据采集方案并分析了4种方案的优缺点；导弹的故障可以归结于部件性能退化，使用基于伪寿命分布的退化数据的处理方法能够很好的评估导弹的可靠性。根据基于伪寿命分布的退化数据分析方法，以方案1的数据进行算例分析，验证了方案的正确性和可用性。

The Reliability Assessment Based On Missile Field Data

Missile is a kind of costly and long-stored equipment. The state of missile can be monitored effectively, but the broken-down time can''t be forecasted. It is needed to use the test data logically for assessing the storage reliability. Now the missile field test data can''t be fully used that cause the problem of superfluous or deficient test. By investigating the test and storage type of missile components, 4 kinds of missile field test data-acquisition projects are brought forward. The advantage and disadvantage of the projects are analyzed. The failure of missile can be ascribed to degraded capability. It is better to use the approach about degradation data analysis based on the pseudo life distribution to assess the reliability. According to the approach, an emulator in which the data of project 1 is used is given. The results validate the validity and practicability of the project.
