摘要
基于流体的波动方程和结构的动力方程 ,利用有限元方法研究了考虑流固耦合时的双层加肋圆柱壳体的振动特性。论文计算了充液夹层圆柱壳体在加肋和不加肋两种情况下的结构模态 ,分析了影响结构振动的主要因素 ,为进一步开展水下航行器的研究提供了一定的依据。
Based on the acoustic wave equation and structural motion equation,the vibration characteristics from the fluid loaded stiffened cylindrical double shell are studied by using finite element method.The structural modes of the cylindrical shell are computed with and without ribs respectively,and the main reasons influenced the structural vibration are analyzed.Some conclusions provide significant references for the continued research for submerged vessels.
