| 摘 要： | 应用商业有限元软件MSC.DYTRAN,比较了2种耦合方法(ALE and General Coup ling),分析计算了球形药包在近似无限水域中爆炸产生的冲击波。对比分析了在不同参数设置下冲击波的传播过程。通过将计算结果与经验公式相比较,证明了MSC.DYTRAN软件是一种合适的模拟水下爆炸冲击波传播的计算分析软件。

| Abstract: | Blast wave produced by sphere TNT charge exploding under similar infinite water region is discussed and computed by using commercial FEM program MSC.DYTRAN.The blast waves are analyzed when different reasonable parameters are adapted.By comparing the simulation result and the empirical result,we can prove that the code MSC.DYTRAN is fit for simulating underwater explosion shock waves. |
