电磁发射复合型结构拦截弹的3维电磁场有限元建模与仿真
Finite element analysis on 3-D electromagnetic field of electromagnetic launching composite intercepting projectile
摘要
Abstract
This paper presents a composite intercepting projectile, which is designed for continuous firing, enhancing intercepting effect and reinforcing driving coil. The 3-D electromagnetic fields in the non-ferromagnet area, ferromagnet area and air area are described by magnetic vector potential and magnetic scalar potential based on Maxwell's equation. The electromagnetic field distribution in the intercepting projectile is then simulated by the MAXWELL3D module of finite element analysis software Ansoft. The simulation results show that, the field distribution of the intercepting projectile with ferromagnet possesses some special characteristics: there exists a repulsion force between induction layer and driving coil, and there exists an attraction force between shielding layer and driving coil. These characteristics make the intercepting projectile meat the design requirements.关键词
