摘　　要：为综合利用海洋空间资源、生物资源以及可再生能源,该文提出一种基于张力腿平台的新型六边形浮体、浮式人工鱼礁以及波浪能装置(WEC)的集成结构系统。基于势流理论,并考虑六边形浮体与浮式人工鱼礁之间的多体水动力耦合效应和机械耦合效应,建立该集成结构系统的耦合时域分析模型。对浮式人工鱼礁和波浪能装置的主要设计参数进行初步优化,重点研究该新型集成结构系统在典型海况下的动力响应和波浪能发电特征,揭示了外侧浮式人工鱼礁可有效减弱作用于内侧六边形浮体结构的波浪载荷,并产生可观的波浪能能源供给。此外,还进一步验证了该集成结构系统在极端海况下的安全性能。A novel modular floating structure combined artificialreef and wave energy converter(WEC)is proposed,so as to make comprehensive use of marine space,biological resources and renewable energy.Considering the multi-body coupling effect and mechanical coupling effect between the hexagonal floating structure and the floating artificial reef,the coupling time-domain analysis model of the integrated structure system is established based on potential theory.The design parameters of the floating artificial reef and the WEC are preliminary optimized.The dynamic response characteristics and the power output characteristics of the new integrated structure system under typical sea conditions are studied.It is revealed that the outside floating artificial reef can produce considerable energy while reducing the influence of wave load on the inside hexagonal floating structure.In addition,the safety of the integrated structure system under extreme sea conditions is further verified.
