摘　　要：分析了螺旋形爆磁压缩发生器的跳匝现象,考虑了膨胀电枢与定子线圈的交线,采用更加精确的计算模型,得出了更为精确的发生器装配公差表达式,通过计算验证了简化模型的结论可以满足设计要求,并对电枢表面和电枢壁厚等的不规则因素,以及圆管爆轰的边缘效应导致跳匝作了深入的分析计算。结果表明:如果电枢的装配公差合适,则可消除由于电枢和定子之间的轴线偏差导致的跳匝现象;圆管爆轰的边缘效应会导致起爆端部分线匝的磁通损失,因而发生器设计时电枢要比定子线圈长一部分;电枢厚度的径向不均匀分布会引起电枢的不对称膨胀,从而导致跳匝发生。The turn-skipping of helical magnetic flux compression generators was analyzed, considering such factors as armature/stator eccentricity, non-uniform of armature surface and thickness, and detonation end effect, etc. Utilizing a more precise calculation model in which the space intersection curve of the expanding armature and the stator was taken into account, a more accurate formula of armature/stator eccentricity tolerance was developed and the conclusion is that the simplified calculation model is precise enough in practice to prevent the turn-skipping. Meanwhile, other factors such as the non-uniform of armature surface and thickness, and the detonation end effect which will also lead to the turn-skipping are also intensively analyzed and calculated. It is concluded that the length of armature should be longer than the stator in the detonating end and the non-uniform of armature thickness should be limited in a certain range to prevent the turn-skipping phenomenon.
