摘要/Abstract

摘要： 多极矩电磁发射是一种新型电磁发射技术，其可调参数多、驱动线圈连接方式灵活的特点对发射效率有较大的影响。从等效电路出发，分析了电枢受力公式及波形匹配问题，并通过电磁场有限元分析研究了不同电压值（电容值）和多级电磁发射情况下六极矩驱动线圈间的连接方式对发射效率的影响。研究结果表明：为了达到较大的发射效率，不同电压值（电容值）需匹配不同的驱动线圈连接方式；在多级六极矩电磁发射情况下，电枢速度改变的同时要改变驱动线圈的连接方式，可以在电容值改变较小的情况下实现较好的波形匹配，从而提高发射效率。

Abstract: Multipole field electromagnetic launcher (MFEL) is a novel electromagnetic launching technology. MFEL has the numerous adjustable parameters and flexible driving coil connection modes, which can significantly affect the efficiency of system. The formula of repulsion force on armature and waveform matching problem are analyzed based on the equivalent circuit model, and the influence of driving coil connection mode on emission efficiency under different voltages (capacitances) and multi-stage electromagnetic launch is studied by using the electromagnetic finite element method. The simulated results indicate that different voltages (capacitances) need to match with different driving coil connection modes in order to achieve greater emission efficiency. In the case of multi-stage sextupole field electromagnetic launch, the driving coil connection modes also should be changed with armature speed, which can realize waveform matching well and improve the emission efficiency with the slight change of capacitance.Key
