摘要
在对称线圈上施加强脉冲电流,在脉冲电流的激励下,线圈中产生感应脉冲磁场,从而实现同极性磁场撞击。在撞击过程中,磁能会以一种波的形式激发出去,从而产生激磁波。激磁波是一种磁性波,其能量主要通过磁场的变化进行传递。利用有限元的方法对对称线圈的内部外部分别进行仿真,讨论并分析了点磁场在空间和时间上的变化。
When pulsed electricity is transiting in symmetrical coils,with the power of pulsed electricity,there will be two inductive pulsed magnetic fields and strike together.This magnetic energy explodes in the way of wave,and produces shock magnetic impulse wave(SMIW).Shock magnetic impulse wave(SMIW) is one kind of magnetism wave,its energy transfers mainly by magnetic field transformation.With the finite element this paper simulates the inside and outside magnetic field of symmetrical coils,analyzes the magnetic field transformation in space and time.
