为了更好地研究水下爆炸冲击载荷，通过数值模拟的方式模拟水下爆炸过程中产生的爆炸冲击波和气泡脉动2种原生载荷。运用有限元软件AUTODYN建立一维炸药-水域模型模拟炸药爆炸产生的爆炸载荷，通过对比经验公式对有限元模型可靠性进行验证，计算结果与经验公式误差不超过15%。同时研究了爆距、炸药当量和水深等变量对水下爆炸冲击波以及气泡脉动的影响。
In order to better study the impact load of underwater explosion, the blast shock wave and bubble pulsation were simulated by numerical simulation. The finite element software AUTODYN was used to establish a one-dimensional explosive-water model to simulate the explosive load generated by explosive explosion. The reliability of the finite element model was verified by comparing the empirical formula, and the error between the calculated results and empirical formula was less than 15%. At the same time, the influence of detonation distance, explosive equivalent and water depth on the shock wave and bubble pulsation of underwater explosion was studied.
