| 摘 要： | 对潜艇结构冲击响应（压力）的分析可以评价结构的抗冲击能力并为提高结构抗冲击性能提供依据。以双层圆柱壳为基础,建立有限元模型。利用仿真算法计算当双层圆柱壳结构在主压载水舱状态改变时,耐压壳与非耐压壳的压力响应,并对压力响应进行了分析。通过数据分析表明：主压载水舱的状态对潜艇主要结构响应有很大影响,尤其是对耐压壳、非耐压壳的压力响应及冲击波过后结构响应的衰减方式、频率都有明显影响。

| Abstract: | The response analysis of submarine under the pressure of shock wave is an important problem that must be considered to achieve anti-shock design of structures during engineering design of the submarine.The FEM model of the double cylindrical shell is established,the pressure response are calculated and analyzed for the pressure hull and non-pressure hull when the state of main ballast tank changed.The conclusions indicate that the main ballast tank has a great effect on principal structure of the submarine,... |
