桥丝式电火工品电磁脉冲效应研究

摘要

In this paper, the electromagnetic pulse(EMP) damage mechanism of bridge-wire electric explosive device(EED) was analyzed, and the test equipment and test method were set up. The bridge-wire EEDs were tested under the excitation of different EMP environment, so the EMP sensitivity of bridge-wire EEDs were obtained. The statistical results showed that the coupling energy should be more suitable for evaluating the effects of EMP instead of the amplitude of exciting source. And the study has certain reference for deep study of EMP protection of EED.%分析了电磁脉冲对电火工品的危害作用机理,建立了研究所需的实验设备和实验方法,并选择某桥丝式电火工品在分布式负载有界波电磁脉冲模拟器下进行了辐射实验研究,从而得到了电火工品电磁脉冲效应敏感度.研究表明采用耦合能量来描述电火工品的电磁脉冲效应敏感度比较合适,所得结论对电火工品电磁脉冲效应及防护技术的深入研究具有一定的参考价值.
