摘　　要：以典型舰船舱室为研究对象,分别建立对应2种打击模式下的多舱室结构模型。采用有限元分析软件,模拟多个舱室结构在内部爆炸冲击载荷作用下的变形和破坏过程,对炸药在舱内爆炸的毁伤特点以及舱室结构的破坏机理进行分析。分析结果表明,舱室结构破坏受炸药装药量、舱壁厚度、初始破口等因素影响,且初始破口对最终破坏效果的影响随着装药量的增加而降低。在对内部遭受较大装药量打击的舰船进行结构毁伤评估时,对于中心处起爆的情况,在进行多舱室建模时,可近似忽略导弹破口的影响,从而方便建模和计算过程。Take the typical warship cabins as research objects,established two kinds of structure models corresponds to two combat modes. Numerical simulation method was carried out to simulate the structure＇s deformation and failure process under the internal explosive load. The damage characteristics of dynamite exploded in the cabin and failure mechanism of structure were analyzed. Results show that cabin structural damage affected by the factors such as the equivalent of explosive,bulkhead thickness,and initial breaks; and the initial breaks＇ effect decreased with the increase of the initial explosive load. When takes damage assessment to a warship which suffered big charge,during the process of modeling,the initial breach caused by missile can be approximated ignored,so as to facilitate the modeling and calculating process.
