摘　　要：为了研究同步感应线圈炮发射过程中的动态特性,建立了考虑驱动线圈级间耦合的五级同步感应线圈炮的机电模型,运用轴对称线圈磁场的数值算法和微分方程算法编写了发射过程动态仿真程序,通过对给定系统发射过程的动态仿真得出了驱动线圈电流、电枢电流,弹丸所受推力、弹丸速度以及位移等重要参数的动态曲线,分析了系统发射过程的动态特性。In order to research the property of multi-stage synchronous induction coilguns, the mechanical and electric model of multistage synchronous induction coilguns was built with thinking about the coupling degree of drive-coils in this paper. The simulation program was compiled with the calculation method of the magnetic field in axisymmetric coils and the differential equations. Dynamic curves of currents changing in drive-coils, currents distribution in the armature, the thrust on the projectile, the velocity and the displacement of the projectile during the launch course were obtained by simulation.
