摘　　要：应用Maxwell方程,建立了轴线起爆螺旋型爆磁压缩发生器(AMFCG)的2维简化理论计算模型。利用此模型,得出了AMFCG中简易磁通表达式,并将等效电路方程与磁通表示结合起来。选用3组不同的几何参数,模拟计算了金属爆炸管在爆轰驱动下的径向膨胀过程,给出AMFCG初始电感、输出电流随时间的变化过程,AMFCG内部磁压、爆轰压及磁场随时间的变化情况。A simplified two-dimension calculation model for helical magnetic flux compression generator with explosive initiated axially（AMFCG） was built by Maxwell equation. By the theoretic model the calculation formula of magnetic flux was simplified, which combined the equivalent circuit equation with magnetic flux expression. The expanding process of the explosive tube radius, the evolution process of AMFCG initial inductance and output current were simulated with three groups of parameters. The competition process between the detonation pressure and magnetic pressure was calculated and the magnetic field distribution was presented.
