摘要: 电热火工品电磁波环境下的电磁感应与能量耦合效应会影响其在武器系统中作用的安全性与可靠性。为了有效地对电热火工品电磁波环境下形成的危害进行衰减与防护,结合电热火工品模拟电磁波环境下的效应试验与规律分析,提出采用铁氧体磁珠器件用于连续电磁波环境危害的防护与适应性设计。试验结果表明,采用脚线串联铁氧体磁珠设计可使电热火工品电磁感应电流有效衰减约30%,且对其桥丝换能元的电热输出性能影响不大,为电热火工品的连续电磁波环境适应性设计提供了一种方法。

Abstract: The electromagnetic induction and energy coupling effects of hot-wire electroexplosive device (EED) in electromagnetic environment have the effects on its safety and reliability. In order to effectively attenuate the effect of electromagnetic environment on EED, the ferrite beads are used in EED for continuous electromagnetic environmental hazard protection and adaptive design threough the effect tests and analysis. The test results show that electromagnetically induced current can be effectively attenuated by about 30%, and the use of ferrite beads can not affect the electric-heating performance of EED, which provides a method for the electromagnetic adaptabilitivity design of hot-wire EED.
