| 摘 要： | 该文建立了磁通压缩发生器的等效电路模型,利用LS-DYNA中的分区算法结合任意拉格朗日-欧拉法(ALE)数值模拟了螺旋形磁通压缩发生器的电枢膨胀过程,得出了不同电枢材料、不同电枢几何尺寸和线圈尺寸下的电枢膨胀角。研究表明,在相同的炸药参数和电枢几何尺寸下,铝电枢膨胀角大于铜电枢,且负载电感上产生的电压也大于铜电枢;铝电枢材料可提高装置的输出电压,而铜电枢材料则能增大脉冲宽度。该文研究可为非核爆磁通压缩发生器输出性能的理论计算提供必要参数,为电枢几何外形设计提供依据。

| Abstract: | An equivalent circuit model of the magnetic flux compression generator is established.The armature expansion process of the helical magnetic flux compression generator is simulated by ALE algorithm of LS-DYNA.The armature expansion angle formed in different armature materials,armature dimension and stator dimension is obtained.The research results show that: in the similar explosives parameters and armature dimension,the aluminum armature expansion angle is bigger than the brass armature expansion angle,and... |
