摘　　要：电磁发射组件基座的材料特性和结构参数变化会影响拦截弹的受力,进而影响拦截弹的发射速度。通过分析电磁发射组件的工作原理,推导了拦截弹的受力方程。编制了有限元分析程序,开发了能够描述发射组件的三维实体模型和有限元模型,对电磁发射组件进行了电磁场仿真。结果表明,基座为磁性材料的电磁发射组件能够减小磁能损失,增大拦截弹的受力;磁性材料基座的结构参数对拦截弹的受力也有影响,故实用中应依据基座材料的特性,合理选择基座的截面尺寸。In the electromagnetic launcher （EML）, both the material characteristic and the structural parameter of its pedestal have influence on the electromagnetic force acting on the interception projectile and then the launching velocity of the projectile are also effected. In this article, the equation of the electromagnetic force acting on the interception projectile is established through analyzing the working principle of the electromagnetic launcher. Then finite element analysis codes are programmed to describe the 3D solid model and finite element model and the electromagnetic field of the EML are simulated. The result shows that when the pedestal of EML is made up of magnetic material lost of magnetic energy can be reduced and the electromagnetic force acting on the interception projectile can be increased. At the same time structural parameters of the pedestal can also have effect on the electromagnetic force. In practice section dimension of the pedestal should be chosen appropriately according to its material characteristics.
