摘要
从研究潜艇壳体表面速度场以及流固耦合作用对双层壳体振动响应特性的影响出发,建立小型有限长双层加肋圆柱壳模型.用有限元法分析了壳体模型在空气中和水中,以及双层壳体间有水三种情况下振动响应特性,分析表明流固耦合作用对壳体,尤其是外壳体低中频段内的振动响应特性影响比较明显,而对高频段的振动响应影响相对较小.
In order to analyze the vibration response and the influence of Fluid-structure coupling for shells of submarine, a model of finite ribbed cylindrical double shell is established in the paper. Analyzed the vibration response of the model by using finite element method on three conditions, which are on vacuum, room between double shells is full with water, and immerged in water. The influence of coupling on vibration response of inner and outer shells is found, which provides some theoretical bases for researching vibration characteristics of the submarine shell and the reconstructing method of the velocity field for outer shell of submarines.
