摘　　要：驱动线圈和弹丸的磁耦合程度对同步感应线圈炮系统效率具有重要影响。通过分析储能脉冲电容器驱动的同步感应线圈炮的工作原理和数学模型,采用了场路耦合的方法进行仿真研究。重点研究了驱动线圈与弹丸线圈几何尺寸、相对位置对同步感应线圈炮磁耦合的影响。仿真结果表明,驱动线圈的内径与弹丸线圈的外径距离越小,驱动线圈有效电流半径与弹丸线圈有效电流半径距离越小,驱动线圈内半径越大,有利于增加驱动线圈和弹丸线圈之间的磁耦合程度,改善系统效率。该研究对于指导同步感应线圈炮设计与优化、开展多级感应线圈炮试验具有一定的参考价值。The magnetic coupling between the driving coil and proj ectile is very important to the efficiency of the synchronous induction coilgun.Through analyzing working process and mathematical model of the synchronous induction coilgun excited by the stored energy pulsed capacitor,the method based on the field-circuit coupled model is adopted to simulate the whole system.This paper emphasizes the influence of the distance between the driving coil and proj ectile,the structure of the driving coil,the inner radius of the driving coil to the system efficiency.The simulation results show that the less distance between the driving coil and proj ectile,the larger of inner radius of the driving coil,the more closer of the current in effect of the driving coil and proj ectile,the more stronger the magnetic coupling,so the efficiency is im-proved.This research can provide reference for induction coilgun design and optimization,developing the experiments of multi-stage induction coilgun.
