摘要: 基于１维爆轰驱动模型、爆炸管与金属固壁的１维磁扩散模型及回路等效电路模型，编制了关于轴线起爆大电流同轴型爆磁压缩发生器的数值模拟程序CEMG2.0。应用该程序对洛斯·阿拉莫斯实验室设计试验的43 cm长Ranchero发生器进行了对比模拟，结果证明CEMG2.0程序所采用的模型是合理的，可以应用于今后同类发生器的优化设计。Abstract: One dimension model of the coaxial explosive magnetic generator (CEMG) has built up. The model consists of 1-D model for explosion driven central tube(armature), 1-D model for magnetic flux diffusion, 1-D model for conductor resistivity and the circuit model. A code (CEMG 2.0) was compiled. With the aid of code CEMG2.0, the 43 cm Ranchero generator designed by LANL has been calculated. The results agrees well with the experiments and the calculation of code RAVEN provided by LANL．
