一种非高压条件下的对称脉冲磁场对撞试验研究

Experimental Study on Interaction of Symmetrical Pulse Magnetic Field Under Non-High Pressure

本文介绍了激磁波的产生机理,并利用麦克斯韦方程对偶极子磁场传播特性进行了理论分析;设计实现了一种基于对称线圈的脉冲磁场对撞试验装置,对比分析了线圈匝数、作用距离等因素对激励脉冲信号的影响。结果表明,试验条件下对称磁场激励信号幅值近似呈1/R规律传播衰减,且在穿透特性上与激磁脉冲波差异较为明显。本文对开展激磁脉冲波的试验研究具有一定借鉴意义。

The generation mechanism of SMIW (Shock Magnetic Impulse Wave) was introduced in the beginning of paper, and the analysis of dual pole magnetic field also be given using the Maxwell equation. Basing on symmetrical coil, a pulse magnetic field collision device was designed and implemented. The influencing factor, such as the coil turns, range of action etc, is compared and analyzed in the test. The results show that, under the condition of the laboratory, the amplitude of the excitation signal is approximately 1/R rule decaying, and the characteristic of penetration comparing the SMIW is different obviously. The paper has some reference significance for the experimental study of SMIW.
