摘　　要：选取现代典型反舰武器和大型军辅船作为研究对象,利用LS-DYNA对典型上层结构在空中攻击武器接触爆炸作用下的毁伤效果进行了数值试验分析,试验结果表明:采用的数值试验方法具有较高的精度,满足工程应用要求;船体上层建筑近炸药结构在空爆载荷作用下直接产生破口和大面积塑性变形,且区域大致呈圆形;近炸药的甲板结构破坏形式与距离爆源稍远的位置处破坏形式不同;船艏舯艉工况毁伤效果相差较大,这与结构形式密不可分。Typical anti-ship weapon and large-scale anxiliary military ship are chosen as the investigated subjects and the damage effect is analyzed by LS-DYNA. The results indicate that numerical experimental methods has high precision which meets engineering demand. The crevasse and plastic deformation occur under the air explosion load and the area is in circular. Damage style is different between the structure near the explosion and the structure away from the explosion and also different is the damage effect of different parts which is related to the structure form.
