摘要
文章旨在探讨用声固耦合算法模拟舰船水下爆炸是可行的.该文应用国际上通用的有限元程序ABAQUS中的声固耦合算法对舰船几种典型的水下爆炸模型进行了计算和分析,总结和分析了采用声固耦合算法进行水下爆炸数值模拟分析时应注意的方法和技巧,并把部分计算数据和实测数据进行对比分析,结果表明:运用数值分析的手段可以比较真实地模拟舰船水下爆炸的实际,计算结果与实测数据基本吻合,可以满足工程要求.对与水下爆炸相关的工程计算有一定参考价值.
Studied is the feasibility of using coupled acoustic-structural analysis to simulate an unaerwater explosion involving a warship. Several models of typical warship underwater explosions were analyzed using the finite element analysis program ABAQUS. The program＇s suitability and methods for numerical analysis of warship underwater explosion are summarized and experimental data is compared. The results show that using this numerical analysis method can simulate the real behaviors of a warship underwater explosion, and the calculations have good agreement with experimental results.
