摘要 常规线圈型电磁发射器的径向应力远大于轴向加速力,因此构建了径向磁场与环向电流作用的多极矩场电磁发射模式;介绍了多极矩场电磁发射器的系统设计,分析了弹射部分和多级加速部分电磁力的产生,基于抛体电流丝法建立了发射系统的机电方程;采用电磁场有限元与瞬态电路耦合法,仿真分析了单级8极矩场电磁发射的瞬态过程;搭建原理性缩比实验,验证了多极矩场电磁发射模式的可行性。

Abstract:The axial acceleration force of the conventional coil electromagnetic launcher is much less than the radial compression force. This paper presents a novel multipole field electromagnetic launcher based on the interaction of radial magnetic field and loop eddy current. The operation principle and conception model are introduced. The electromagnetic acceleration forces of eddy-current catapult and induction acceleration are analyzed. Based on the current filament method, the system dynamic equations are established. By electromagnetic field finite element analysis coupling with circuit, the transient launch process of single stage of octupole field coil electromagnetic launcher is simulated. The experiment results of the principle prototype indicate that the multipole field coil electromagnetic launcher is feasible.
