摘　　要：为了探讨单级线圈炮发射过程中电感随位置变化的规律,依据线圈炮的基本原理和有限元分析方法,利用电磁场计算软件,分析了单级线圈炮发射过程中的磁场分布情况,并探讨了不同的抛体电枢形状对系统电感梯度的影响.经过模拟分析,得出了系统电感及电感梯度与抛体电枢位置的关系和合理的抛体电枢与定子线圈的形状.According to the basic principle of the coilgun and finite element analysis, the magnetic field of a single - stage coilgun is calculated by using the finite element software. The influence of the shape of projectile on the inductance gradient of the coligun has been taken into account. Then the relationship of the inductance of the coligun and the position of projectile, the relationship of the inductance gradient of the coligun and the position of projectile has been obtained. The reasonable shape of the stator coil and projectile also has been obtained.
