摘要 利用LS-DYNA动力有限元程序对张效慈等人做的深水爆炸水动压力场对潜体结构的动态响应试验进行数值模拟,其模拟结果与实际具有较好的一致性;同时模拟了不同厚度圆柱壳在不同质量炸药爆炸情况下所表现的抗冲击性,为提高潜艇的抗冲击性提供参考。 The experiment of dynamic effect of ship structure produced by underwater shock and explosion bubble has been numerically simulated with LS-DYNA. The simulation result basically accords with the data of experiment. Anti-impact is simulated in the case of different wall thickness of cylinder shell and different quantity of explosive which provides some reference for design of submarine.
