摘要

摘要: 针对美军标中提出2.3/23 ns核电磁脉冲辐射作用会对武器系统及电火工品造成严重威胁的问题, 利用电火工品核电磁脉冲辐射效应试验系统, 展开其在电磁脉冲辐射作用下安全性研究, 获得了火工品的桥丝电阻和脚线长度与电磁脉冲辐射作用下的感应电流和感应能量关系。研究结果表明, 桥丝电阻消耗能量的速率一定, 当桥丝电阻逐渐增大时, 电阻消耗的能量不断增多, 感应能量随桥丝电阻的增大线性增大; 桥丝上的感应电流峰值主要由等效天线的等效阻抗决定, 桥丝电阻改变基本不影响峰值感应电流; 峰值感应电流随脚线长度的增大线性增大, 感应能量随脚线长度增加呈指数增大关系。文中研究可为提高电火工品核电磁脉冲效应适应性提供设计依据。

Abstract: To solve the problem that the 2.3/23 ns high-altitude nuclear electromagnetic pulse(HEMP) radiation proposed in United States military standard can seriously affect weapon system and electric explosive device(EED), the testing system of HEMP radiation effect was employed to perform safety research on EED under electromagnetic radiation. The relationships of bridge-wire resistance and foot line length of EED with the induced current and energy under HEMP radiation were obtained. The results show that: 1) the energy consumption rate of the bridge-wire resistance is constant; 2) the energy consumed by the resistance rises and the induced energy rises linearly with the bridge-wire resistance; 3) the peak induced current in bridge-wire depends on the equivalent impedance of equivalent antenna, and the change in bridge-wire resistance will not affect the peak induced current; and 4) the peak induced current increases linearly with the foot line length, and the induced energy increases exponentially with the foot line length. This research may provide design basis for improving the adaptability of EED to nuclear electromagnetic pulse effect.
