| 摘 要： | 为研究水底爆炸后冲击波峰值压力特性,在对其理论分析的基础上,采用了AUTODYN软件基于ALE和多物质场欧拉2种算法对炸药在水底爆炸冲击波压力进行了数值计算,2种方法计算结果吻合;与在无限水域条件下采用经验公式计算结果相比数值计算结果较大,说明海底的反射作用增大了水中的冲击波压力.

| Abstract: | For studying the characteristic of shock wave peak pressure of under water explosion and based on the theoretical analysis,the ALE and multi-Euler numerical simulation method in AUTODYN were applied to simulate the explosive exploded under water,and the results of two methods was consistent.Those results were larger than the results calculated by the empirical formula of explosion in infinite water,which shows that the reflect effect of the water bottom enlarge the pressure of water shock. |
