摘　　要：在文中设计中,串联增强型六极轨道电磁发射器可获得高的电感梯度和良好的磁屏蔽效应,这些性能在新型电磁发射器中起着重要作用。由于电感梯度是影响超高速发射和降低大电流的决定性因素,因此文中设计了一款新型电磁发射器并研究了电感梯度在双抛体运动区域的分布问题。在文中研究中,将提出3种典型串联增强型六极轨道的连接方式,并采用有限元模拟进行比较分析。理论分析和数值仿真结果表明,A构型的磁屏蔽和电感梯度性能优于其它两种构型配置。In this paper,series-connected augmented sextupole orbit electromagnetic launcher was designed to obtain high inductance gradient and good magnetic shielding effect,which played an important role in the new type of electromagnetic launcher.Since the inductance gradient was the decisive factor that affects the hypervelocity launch and reduced high current,a new type of electromagnetic launcher was designed and the distribution of the inductance gradient in the motion region of the double projectile was studied.In this study the connection modes of three typical series-connected augmented sextupole orbits were presented and compared by finite element simulation.The theoretical analysis and numerical simulation indicate that the magnetic shielding and inductance gradient performance of the A configuration are better than those of the other two configurations.
