【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。
[Abstract]:In order to analyze the bottom slamming problem of offshore wind power equipment installation ship with special ship type, this paper presents a flow chart for calculating the bottom slamming load of wind power equipment installation ship. Based on the theory of wave potential current, the motion response of ships with speed in waves is calculated, and the time history curve of vertical velocity of a typical section before and after entering water is fitted by polynomial. Based on the theory of computational fluid dynamics (CFD), the water slamming load of two-dimensional ship profile is numerically simulated. Then, the accuracy of ship motion response and two-dimensional section water injection algorithm is verified by comparing and analyzing the experimental data of the key links in the calculation process. Finally, the bottom slamming characteristics of offshore wind power installation ship are studied according to the calculation method.
