中文摘要：
为了分析具有特殊船型的近海风电设备安装船的底部砰击问题,论文提出了一种适用于风电设备安装船的底部砰击载荷计算流程.其中,基于波浪势流理论计算有航速船舶在波浪中的运动响应,利用多项式拟合典型剖面在入水前后时刻的垂向速度时间历程曲线,基于计算流体力学理论数值模拟二维船型剖面入水砰击载荷.然后,针对计算流程中的关键环节进行实验数据对比分析,验证了船舶运动响应和二维剖面入水算法的准确性.最后,根据论文计算方法对近海风电设备安装船的底部砰击特性进行研究.
英文摘要：
A computation procedure is proposed for slamming load on offshore wind turbine installation vessel （WTIV）. Motion response of the vessel in waves is computed based on potential wave theory, and vertical velocity of a 2D cross section during water-entry is handled with polynomial fitting method. Slamming load on the section is numerically simulated with computational fluid dynamic （CFD） method and compared with experimental data, which verifying the accuracy of numerical algorithms. With the present method characteristics of slamming load on the vessel are studied.
