本文通过建立特定船型的三体船三维砰击模型，运用计算流体力学软件Fluent中的动网格技术对其进行在一定航速下的数值模拟，得到特定航速下三体船主体船体、侧体船体和连接桥在砰击下的压力分布以及船体附近流场的变化。然后结合流场、压力等的变化分析该三体船船型在砰击下的动力响应。
In this paper, a certain trimaran 3-D slamming model is built for numerical simulation analysis and dynamic mesh technique is used for achieve the sailing simulation at a certain speed in FLUENT. Then we obtain the slamming pressure distribution of main body, lateral body and cross structure, the variation of flow field near the trimaran could also be observed. Finally the dynamic response under slamming would be analyzed on the basis of flow field and pressure variation.
