径向磁场与环向电流作用的电磁发射模式
Multipole Field Electromagnetic Launch Model Based on Radial Magnetic Field Interact with Loop Eddy Current
摘要
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.关键词
