摘　　要：目的:采用5MW-OC04半潜式浮式风机平台作为参考模型,研究聚酯缆作为系泊缆材质对于浮式风机平台动力响应的影响。方法:使用AQWA建立半潜式浮式风机平台模型,使用聚酯缆作为系泊缆材质,对比研究在南海一年一遇海况下系泊缆的改进对于浮式风机平台动力响应的影响;在此基础上,基于南海百年一遇的海况对浮式风机平台进行优化。结果:在对系泊方案进行优化之后,各项动力响应均呈现一定程度的减小,其中纵摇振幅从6.64 m降至4.7 m,最大张力从6.56 MN降至4.65 MN。结论:较之传统方案,该方案能改善浮式风机平台的动力响应。Aims:The influence of polyester cables on the dynamic response of the platform was studied with a reference of the 5MW-OC04 semi-submersible floating wind turbine platform.Methods:Aqwa was used to establish the model of semi submersible floating fan platforms;and the frequency domain analysis method was used to calculate the dynamic response of the platform to obtain the frequency domain amplitude response curve of the platform.The accuracy of the established model and data analysis was verified by comparing with the experimental data of similar models.Using polyester cable as the mooring line material,the influence of mooring line improvement on the dynamic response of a floating wind turbine platform under the once-in-a-year sea state in the South China Sea was compared and studied.Results:Based on this,the floating wind turbine platform was optimized according to the once-in-a-century sea conditions in the South China Sea.Conclusions:The optimization results show that the scheme can improve the dynamic response of the floating wind turbine platform compared with the traditional scheme.
