| 摘要: |
| 建立了爆炸磁压缩装置（FCG）的2-D轴对称有限元模型，应用显式非线性动力分析程序进行求解，得到了爆磁压缩装置电枢膨胀过程的图像。电枢使用Johnson-Cook材料模型和根据实验Hugoniot曲线确定的Grüneisen状态方程，考虑到了材料应变率硬化和塑性功绝热加热过程；炸药材料采用JWL状态方程，得到了铝金属管电枢的膨胀过程、膨胀张角以及塑性功导致的电枢温度升高。 |

| Abstract: |
| A 2-D axisymmetric nonlinear explicit finite-element dynamic analysis program is applied to compute the armature expansion process of the magnetic flux compression generator (FCG). The temperature rising and thermal softening are considered as Johnson Cook material is used for the armature. The results present the picture of expansion process of the armature, the expansion angle and temperature rising. |
