摘　　要：针对5MW海上风机,进行了半潜型浮式基础的概念设计,研究了其幅频运动特性。考虑风机浮式基础的稳性和运动要求,对浮式基础的构件进行设计,并进行舱室划分;考虑叶片产生的气动载荷影响以及风载荷作用,计算分析风机浮式基础的完整稳性及破舱稳性;考虑浮式基础构件及压水板的粘性阻尼,计算浮式基础的幅频运动响应特性。计算结果表明,设计的浮式基础运动性能满足风机发电作业的要求。A floating foundation is designed to support a generic 5MW wind turbine, and its frequency domain characteristics are studied. According to the stability and motion, columns and bracings are designed, and the compartments are divided. Taking the aerody- namic load produced by blades into account, intact stability and damaged stability are studied. Considering the viscous damping of water entrapment plates, the amplitude-frequency responses are calculated. The results show that the motion performance of the floating foundation can meet relevant requirements.
