舰船舱内爆炸载荷简化载荷计算模型

Simplified calculation model for explosion loading in ship cabin

为得到舱内爆炸载荷简化计算方法,将舱内爆炸下目标壁面受到的内爆载荷在时间分布上分为爆炸冲击波作用和准静态压力作用2个阶段,在空间分布上分为非角隅中间区域、两面角隅区和三面角隅区,建立了舱内爆炸下目标壁面所受载荷的简化计算模型,并通过Matlab编程实现,得到目标壁面受到的舱内爆炸载荷总冲量,其结果与数值仿真结果吻合较好。该简化模型可用于舰船舱内爆炸载荷强度及壁面总冲量的快速工程估算。

In order to obtain a simplified calculation method for the explosion load in the cabin,the implosion load received by the target wall under the explosion in the cabin is divided into two periods:the explosion shock wave period and the quasi-static pressure period.The spatial distribution of the loading is divided into the center area,the dihedral corner area and the trihedral corner area.The simplified calculation model of under the explosion loading in the cabin is established,and the total impulse on the target wall is obtained by Matlab programming of the simplified method.The results areconsistent well with the numerical simulation results.This simplified model can be used for rapid engineering estimation of explosive loads in ship cabins.
