为解决传统的自升式风电安装船难以满足浮式风机的安装要求问题，参考起重船的参数，设计了漂浮式海上风电安装船。建立了风电安装船-吊臂-吊钩-叶片系统多刚体模型和浮式风机系统单刚体模型，编写了数值仿真程序，计算了不同海况等级下进行吊装作业时叶根与轮毂之间相对位置的变化。结果表明，海况等级的提高会使叶根与轮毂之间的相对运动标准差增大，应尽量避免在高等级海况下进行海上浮式风机叶片安装作业，且应避免在横浪条件下进行侧吊安装作业，以防叶根与轮毂的纵荡运动幅值过大或发生碰撞。
In order to solve the problem that the traditional jack-up wind power installation ship is difficult to meet the installation requirements of floating wind turbines, a floating offshore wind power installation ship is designed with reference to the parameters of the crane ship. A multi-rigid body model of wind power installation ship-boom-hook-blade system and a single rigid body model of floating wind turbine system are established, and a numerical simulation program is written to calculate the changes of relative positions between the blade root and the hub when lifting operation is carried out under different sea state levels. The results show that the standard deviation of the relative motion between the blade root and the hub increases with the increase of sea state level, and the blade installation of floating wind turbine should be avoided under the high sea state level, and the side lifting installation should be avoided under the condition of transverse waves, in order to prevent the amplitude of longitudinal oscillatory motion between the blade root and the hub from being too large or collision.
