摘要
定子线圈中的电流在空间中产生的磁场是金属导体(套筒)膨胀压缩的主要对象,该磁场直接影响爆磁压缩发生器输出电流脉冲的大小。给出了面电流分布下2维磁场的计算公式,较点电流分布下的磁场公式更能细致准确地反映出磁场的变化。数值结果表明:面电流分布下的磁场公式不仅能准确地描述磁场的变化,而且计算效率大大提高,节约了计算时间。
In an MFCG, the magnetic field generated by the current of stator coils is compressed by the expanding armature. It is important to compute the value of the magnetic field exactly, for it is relevant to the output current of MFCG. Formulas of magnetic field with surface current density and that with point current density are presented. Numerical results prove that the former can describe the magnetic field more accurately than the latter, and the former is more efficient than the latter.
