摘　　要：漂浮式风电是深远海风能资源开发、实现双碳目标的重要途径。针对我国沿海海域情况,开展深远海漂浮式风电浮体概念设计,探讨浮立柱数量、下浮体形状等对浮体整体受力的影响,并在此基础上,采用拓扑优化算法进行浮体构型优化。结果表明,三立柱半潜式浮体制造简单、稳定性强,采用环形旁通构型能够提升垂荡自然周期,避开波浪能量集中范围,降低浮体响应。Floating offshore wind turbines are an important pathway for the development of deep-sea wind energy resources and achieving peak carbon emissions and carbon neutrality goals.Based on the coastal waters of China,the conceptual design for deepsea floating offshore wind turbine foundations was conducted,and the effects of the number of floating columns and the design of the substructure on the stability of the foundation structure were analysed,and the structural optimization was realized by using topology algorithms.The results show that three-column semi-submersible floating wind turbines offer both simplicity in manufacturing and strong stability,and the toroidal shape enhances the natural heave period of floating wind turbines,avoiding wave periods,thereby achieving reduced dynamic response.
