摘　　要：对于多级同步感应线圈炮来说,比较成熟的模型是基于电流丝方法建立起来的机电模型,它的优点是计算速度快,缺点是无法考虑线圈炮的外围结构和材料特性对其产生的影响.论文推导给出了总体采用矢量磁位A、电路中的驱动线圈中电流I作为求解对象的场路耦合瞬态电磁场模型,利用节点力法计算电枢所受的电磁力,根据电枢运动学模型,进一步推导出耦合运动的多级感应线圈炮的机电模型,并进行有限元离散求解.应用上述模型对5级感应线圈炮进行分析,计算结果与实验结果相吻合,验证了该模型的正确性.For Multi-stage synchronous inductive coil gun, the el rent filament method is well known. As know, this model has very h consider the effect of the peripheral structure and the material of coil transient electromagnetic field-circuit-moving model of multi stage ind magnetic potential A and I the current in the circuit as variables. All by employing the nodal force method. According to kinematics mo ectromechanical model based on cur- igh calculation efficacy,but does not gun. In this paper,we propose a 3D uctive coil gun by adopting the vector electromagnetic forces are calculated of armature,a finite element analysis （FEA） model coupling the circuit field and movement used in analyzing multi-stage inductive coil gun is presented in this paper. The performance of a 5 stage inductive coil gun is analyzed by using the present model, The calculation result shows good agreement with the experimentally measured results.
