引信自炸定时电路抗掉电分析

摘要

According to the phenomenon, the mis-triggering reason of the fuze self-destruction timing circuit for instantaneous power failing is indicated. In this paper, working principle and characteristics of the fuze self-destruction timing circuit is analyzed, the reason of the mis-triggering is found out. The influence of fuze self-destruction timing circuit caused by power fail is simulated. This article makes some optimization for the corresponding power circuit. The validity of the project is verified by the simulation and experimental results.%某引信电源短时间掉电而引起自炸定时电路误触发的故障现象,本文通过分析引信自炸定时电路的组成和工作原理,找出自炸信号误触发的原因;在此基础上,建立基于Saber的自炸定时电路仿真模型,仿真引信电源短时间掉电对自炸定时电路的工作产生的影响,优化电路提高引信自炸定时电路抗掉电能力,并通过仿真验证了优化措施的有效性。
