摘　　要：海上救助往往伴随着一定的风险性,尤其在深远海恶劣海况下,无论是对于救助船或被救助船来说,安全的救助就显得尤为重要。为了保障救助过程中的安全性,需要预测船舶并靠过程中的运动响应。本文基于N-S方程建立了数值造波水池,并利用嵌套动网格技术模拟了两艘船舶的6自由度运动。研究在横浪情况下,不同浪高对双船耦合运动的影响,并考虑了船舶甲板上浪等情况。Rescue and salvage in the sea are always dangerous.If the accident occurs in a terrible environment condition,the safety for not only the accident ship but also the rescue ship is hard to be guaranteed.In order to solve the problem,a prediction of the response is necessary for two side-by-side ships.Based on the Navier-Stokes equations,a three-dimensional numerical pool is established.By using the overset method,the ship motion of two Wigley models in beam sea is researched.Different wave height is set,and the situation of green water is considered.
