| 摘 要： | 通过数值仿真,根据螺旋线圈电磁发射器(HCEL)驱动线圈的径向磁场分布,提出一种"D"形截面电枢并确定其最佳受力位置.计算表明,相同线度的"D"形电枢比矩形电枢加速度更大,即在炮长(弹丸加速长度)相同的情况下,"D"形电枢比矩形电枢具有更高的出口速度.以"D"形电枢为例,分析了弹丸线圈与驱动线圈上的轴向、径向受力分布....

| Abstract: | The radial magnetic field distribution of the helical coil electromagnetic launcher's driving coil is investigated by numerical simulation,from which a D shaped cross section armature is proposed and its best location is determined.The results show that,with the same size,the acceleration of the D shaped armature is bigger than the rectangular armature,i.e.,with the same length of the launcher,the muzzle velocity of the D shaped armature is bigger than the rectangular armature.Taking the D shaped armature a... |
