摘　　要：以某水中目标为研究对象,采用数值计算方法对其在反制武器攻击下的毁伤情况进行研究。首先,对仿真方法的正确性进行验证,保证计算方法的正确性;其次,假定水中目标受到灭雷弹攻击,建立水中目标的仿真计算模型,采用ABAQUS显式动力学方法计算方法,以灭雷弹毁伤半径、水中目标本身抗炸指标设计计算工况,以壳体破裂为判据,对水中目标受到灭雷弹攻击的毁伤情况以及抗水中爆炸的毁伤情况进行了数值仿真计算。结果表明:壳体内部是否装药对损伤影响很大,壳体内部没有填充物的情况下,水中目标抵抗炸雷弹攻击的能力比较弱;爆炸方位对毁伤效果存在一定的影响,侧面起爆对目标结构毁伤程度大于后方起爆。The anchored object is selected as subject investigated.The damage status of that is researched using numerical simulation,which is attracted by the counter weapons.First,validity of simulation method is testified.Second,assuming the object is attracted by the counter weapon and the simulation model of the object is founded.Third,the counter weapons'damage status of mine and anti-under-water explosion have been computed,by using ABAQUS hydro-dynamics simulation method.Calculate conditions of the object have been designed by combining the damage zone of the counter weapon,anti-explosion characters of the object and object shell broken criterion.It shows that it is very different whether or not stuffing explosive in object shell.If the object shell inner is empty,its ability to anti-explosion is weaker.The explosive position has big effect on the damage of the anchored object.The later⁃al explosion is stronger than rear explosion.
