| 摘 要： | 在炸药爆炸驱动飞板碰撞厚钢板后，利用二维动态有限元数值分析方法对厚钢板自由面的速度进行了数值计算，还利用钢板和空气界面条件对钢板背面空气中冲击波的传播进行了一维球对称的数值分析，所得的结果与实际测量值吻合较好。

| Abstract: | The velocity at the free face of a thick steel plate impacted by an explosive plate is calculated by means of the two-dimension dynamic finite element analytical method. And one-dimension spherical symmetry method is also used to analyze the characteristics of shock wave propagation in air behind thick steel plates under interface condition of thick steel plates and air. The results are in a good agreement with the experiments. |
