| 摘 要： | 采用二维解析和一维离散的方法处理无限流体介质，建立一种分析结构与外流体动力相互作用问题的半解析无限元法，使波浪对弹性结构绕流的三维问题化为一维数值问题来解，从而在很大程度上节省了单元、内存与计算工作量，同时径向无限域边界可得以正确模拟，比现有的有限边界人工处理更显优越。

| Abstract: | For structure-fluid dynamic interaction problems,a semi-analytical infinite element method is presented in this paper.The pressure function of infinite fluid meduim is analytical in two directions and discrete in another one,then three-dimensional interaction problem of surface wave flow over elastic structure is reduced to one-dimensional one.The number of elements,core requirement and the cost of computation are reduced considerably,and the infinite boundary in the radial direction is now modeled more accurately in comparison with some current methods,in which artificial finite boundary is placed. |
