【摘要】 针对当前引信电子安全系统失效率分析中可恢复安全系统失效率研究较少的现状，根据引信可恢复安全系统解保及恢复逻辑图，通过状态转移的方法，对引信飞行弹道安全性、恢复安全特征识别等过程进行安全失效率分析与计算，得出两道静态保险解除后失效率最高，且可恢复安全系统的失效率略大于传统不可恢复安全系统。通过对安全系统待发状态下失效率的计算，得到的计算结果可以给引信可恢复安全系统失效率标准的建立提出数据支撑。更多还原

【Abstract】 In the failure rate analysis of current fuze electronic safety system, research about the failure rate of recoverable safety-and-arming system is not so much. In this paper, the safety failure rate of fuze was analyzed and calculated in the process of flight trajectory safety and recovery safety feature recognition by state transfer method. The result of analysis and calculation showed that the two static safeties had the highest failure rates when they were disengaged, and that the failure rate of the recoverable safety-and-arming system was slightly higher than that of the conventional non-recoverable safety-and-arming system. By calculating the failure rate of the safety-and-arming system in the pending state, the obtained calculation results could present data support for the establishment of the failure rate standard of the fuzed recoverable safety-and-arming system.更多还原
