摘　　要：在磁阻型线圈发射器的发射过程中,对发射器的驱动线圈装夹轭铁提高弹丸的炮口初速,并利用ansoft maxwell有限元软件,对没有轭铁和添加轭铁两种情况下的二级磁阻线圈发射器进行仿真,对比不同的轭铁装夹方式对炮口初速度的影响。结果表明:二级线圈添加轭铁以后,弹丸的炮口初速得到提升;相比较两个线圈添加一整块轭铁的方式,线圈分别添加轭铁的情况时其弹丸的提速更加明显,所受到的电磁力更大。In type magnetic resistance coil launchers firing process,the study of the methods to improve the muzzle velocity of projectile is put forward for the launcher of drive coil clamping yoke iron way using ansoft finite element software of maxwell no yoke iron and add a yoke iron in both cases the secondary magnetic resistance coil launcher,simulation analysis in both cases the muzzle velocity of projectile. The results showed that the muzzle velocity of the projectile was improved after the yoke was added. Compared to the two coils,the coil is added with a single yoke,and the coil is added with the yoke and the acceleration of the projectile is more obvious and the electromagnetic force is greater.
