摘　　要：本文针对尾压浪板入水砰击压力开展研究,分别用Fluent和Dytran软件计算其入水砰击载荷。本文首先在不同的有限元模型中计算尾压浪板以10 m/s入水时的砰击压力,选择具有合理网格尺寸的有限元模型,进而避免了网格尺寸对计算结果的影响;接着分别计算了尾压浪板以不同速度入水时所受到的砰击压力,二者计算得到的砰击压力系数与我国规范给出的结果较为吻合,对于船舶尾压浪板砰击载荷的选取具有一定的参考意义。This paper mainly do some study about the slamming pressure of the wave suppression board when it entry water. This paper calculates the load induced by slamming with software of Fluent and Dytran. Firstly,this paper calculate the slamming pressure of wave suppression board when it entry water with speed of 10 m / s in different finite element model. The reasonable mesh is obtained through this method. This method could avoid the negative influence of grid＇s scale on the result of slamming pressure.Then this paper calculate the slamming pressure of the wave suppression board when it entry water with different speed. The coefficient of slamming obtained by calculation agrees very well with the standard launched by CCS. This has some significance for the choice of slamming load.
