| 摘 要： | 为研究水下爆炸气泡溃灭发生射流时对结构的影响,借助有限元软件MSC.Dytran对固支方板在水下爆炸载荷作用下的动态响应进行研究。对底部爆炸和侧面爆炸两种典型情况进行计算,对射流发生时流场情况以及固支方板的响应特点进行分析,认为射流载荷是局部载荷,会引起严重的局部破坏,在近场水下爆炸研究中必须予以重视。

| Abstract: | In order to study the effect of the liquid jets from collapsed bubble to the structure, MSC. Dytran was used to simulate the dynamic response of clamped square plate subjected to the underwater explosion. The explosive was placed under or on the sides of the structure. The flow field conditions and response of the clamped square plate were analyzed. The load of jets can cause the local damage to the structure, Therefore it has to be considered in near field explosion research. |
