| 摘 要： | 针对水下爆炸作用下舰船底部液舱的动态响应,采用数值方法进行研究。借助有限元程序ABAQUS对1个简单液舱板架结构模型的动态响应进行数值仿真分析,比较了空舱、满载液舱、半载液舱和单层底这4种情况,分析了各层板中点处的压强、应力及加速度等动态参数。结果表明,半载液舱的防护效果最好,能同时缓解水下爆炸对外底板和内底板的冲击作用。

| Abstract: | Using the numerical method to study the dynamical response of ship's liquid cabins under explosions.Adopting the software ABAQUS to simulate the dynamical response of a simple liquid cabin model.Four conditions,including vacant cabin,fullload liguid cabin,halfload liguid cabin and monolayer plate-shell,were compared.Also,the pressure,stress and acceleration of the plates'centre were analyzed.It reveals that the existence of half load liquid cabin is the best,because it can both reduce shock to the out plate... |
