Optimization of the Drive Coil in the Multi-Stage Synchronous Induction Coilgun

摘要:

在多级同步感应线圈炮系统中,驱动线圈的轴向长度将会直接影响弹丸的速度。文中采用轴对称线圈磁场的数值算法和微分方程的前向差分法,对三级同步感应线圈炮系统中驱动线圈的轴向长度与弹丸发射速度的关系进行了仿真分析,得出了驱动线圈的最佳轴向长度。

Abstract:

In the system of the Multi-Stage Synchronous Induction Coilgun, the axial length of the drive coil directly affects the velocity of projectile. In this paper, the relation between the axial length of drive coils and the velocity of projectile in the three-stage synchronous induction coilgun system was simulated and analyzed with the calculation method of the axisymmetric magnetic field and the forward difference procedure of differential equation. The optimal length of the drive coil was gained.
