| 摘 要： | 对具有双层壳体结构的潜艇状水下航行体的纵向振动特性进行了研究。采用有限元方法计算了纵向振动湿模态的固有频率和振型，发现该水下航行体内层壳板具有两种典型的纵向总振动振型：“振动节面振型”和“错动块振型”，而外层壳板以局部振动为主。

| Abstract: | In this study, the longitudinal vibration characteristics of underwater submarine - shaped vehicle with double-hull are investigated. The finite element method is applied to calculate natural frequency and draw out the longitudinal vibration mode. The results show that the inner shell of this underwater vehicle has two typical longitudinal global vibration modes, that is vibration nodal plane mode and thrown block mode, while the outer shell gives priority to local vibration. |
