以5,MW 风机为模型，概念性地设计了一种新型海上风机浮式平台。基于三维势流理论和 Morison 经验公式，利用 HydroD 软件计算了浮式平台的水动力系数；根据悬链线理论，编程计算了系泊系统提供的回复刚度；考虑风机与平台、系泊系统与平台之间的耦合以及黏性阻尼的影响，在频域范围内编程计算了风机系统的运动响应，得到新型浮式平台的幅频响应曲线，并在此基础上研究了波浪入射角、水深等因素对浮式平台运动的影响。结果显示，在波浪角为0°时运动响应最大，且浮式平台更适用于较大水深。

Taking a 5,MW wind turbine as an example,a new type of floating platform for offshore wind turbine was designed conceptually. Based on potential theory and Morison equation,the hydrodynamic coefficients were com-puted using HydroD software. The restoring stiffness provided by mooring system was calculated by program using catenary method. By considering the coupling effects of wind turbine,mooring system and platform,as well as the effect of viscous damping,the dynamic responses in frequency domain were computed by program,and then the amplitude-frequency response curves were obtained. Furthermore,the effects of incidence angle of wave and water depth on the responses of the platform were studied. The result showed that response of move of wave reached max-ium at the angle of zero deyree, and the floating platform was suitable for profoundal zone.
