摘　　要：以双脚线电火工品为研究对象,结合实际装备的双脚线可能呈现一定夹角的情况,建立了双脚线耦合天线模型,通过理论分析和数值仿真获得了不同夹角情况下天线方向图、反射系数、增益的变化对于耦合电流及耦合能量的影响规律,并通过实验进行了对照验证。研究表明,双脚线电火工品的引线夹角在60°以上时,耦合电流及能量随着角度增加而快速上升;双脚夹角到90°时,耦合能量已经数十μJ;夹角为180°时,耦合能量达到峰值。Based on the model of the coupling effect of the high-altitude electromagnetic pulse(HEMP) radiation field on the electric explosive device and the antenna configuration analysis, this paper analyzes the influence of antenna pattern, reflection coefficient and gain changes on coupling current and coupling energy at different angles. The results show that the coupling current and energy increase rapidly with the angle when the angle between the two pin wire exceeds 60° When it reaches 90°, the coupling energy would increase to tens of μJ, which brings certain safety risks. When the included angle rises to 180°, the coupling energy will reach the peak.
