Multipole field reconnection electromagnetic launcher (MFREL) is an electromagnetic launcher (EML) with excellent performance, which has good application prospects in both military and civil fields. The selection of the appropriate trigger position can launch the projectile with higher speed and efficiency. The influence of capacitance parameters on the optimal starting position is studied in this article. The launch model and relevant theories are first introduced, followed by a series of simulations to investigate the performance of the model. The results indicate that the optimal trigger position is inversely proportional to the capacitance and voltage, but, because the change of capacitance value affects the discharge time constant of the current curve, the influence of capacitance value on the optimal trigger position is greater than that of voltage. The simulation results provide a reference for the selection of the best trigger position for reconnection electromagnetic launcher (REML) under different capacitance parameters.

多极场重连式电磁发射器最佳触发位置的电容器参数研究

多极场重联电磁发射器（MFREL）是一种性能优良的电磁发射器（EML），在军事和民用领域都有很好的应用前景。选择合适的触发位置可以以更高的速度和效率发射弹丸。本文研究了电容参数对最佳起始位置的影响。首先介绍了发射模型和相关理论，然后通过一系列仿真来研究模型的性能。结果表明，最佳触发位置与电容和电压成反比，但由于电容值的变化影响电流曲线的放电时间常数，电容值对最佳触发位置的影响大于电压。仿真结果为不同电容参数下重连式电磁发射器（REML）最佳触发位置的选择提供了参考。
