为提高多级同步感应线圈发射器的加速性能，以5级同步感应线圈发射器为例，在定义驱动线圈极性相对排列方式的基础上，基于场-路耦合的时步有限元分析方法，研究了驱动线圈极性排列方式对其加速性能的影响，结果表明：驱动线圈同极性相对排列方式更有助于提高发射效率。通过分析内部磁场的分布规律，探讨了驱动线圈同极性相对排列方式改善加速性能的原因，最后通过比较电枢内的感应电流密度的方法验证了分析的正确性。

In order to enhance accelerative performance of multi-stage synchronous induction coil launch-er,taking the five-stage synchronous induction coil launcher as an example,based on the conceptions of polarity arrangement manner of driving coil,the influences of polar arrangement manner of driving coil on the accelerative performance are studied by means of time-step finite element analysis in accordance with the coupling of magnetic field and circuit.Research shows that the opposite arrangement manner with the same polarity is more helpful to enhancing launch efficiency than the opposite arrangement manner with different polarity.The reason that leads to enhancing launch efficiency is explored through analysis of the inner magnetic field’s distribution.The correctness of the analysis is validated by comparison of current density in the armature.
