摘　　要：为了快速有效地实现电磁轨道炮的反导,对其固体电枢电磁阻力与空气阻力角度等运动进行研究。在基于麦克斯韦理论的基础上,分析了电枢在炮管内的力学特性。通过理论仿真计算分别对电枢的电磁阻力及空气阻力进行了分析,比较了截面及摩擦因素对出口动能的影响,得到了最优方案,并提出了改进电枢发射的措施。研究结果表明:低速段摩擦力大于空气阻力,而高速段空气阻力对发射影响较大。In order to quickly and efficiently realize the anti-missile of electromagnetic rail gun, the air resistance and magnetic resistance of solid armature were studied. Based on the Maxwell＇s theory, the mechanics properties of the armature in the gun tube are analyzed. By theoretical and simulation respectively to the armature resistance and electromagnetic air resistance are analyzed, the cross section and the influence of friction factors on the export of kinetic energy are compared, the optimal solution is got, and the measures of improving the armature launch are put forward. The results showed that low speed friction is greater than the air resistance, while the high speed period of air resistance has a greater impact to the mission.
