摘　　要：中国海岸线绵长,海上光伏可装机规模巨大,海上浮式光伏平台受到广泛关注。为了发挥规模优势及经济效益,其通常被设计为联排形式。针对浮式联排光伏平台开展了系统性的数值分析,研究了刚性和柔性两种连接件设计形式。针对刚性连接件,研究释放不同转角约束下浮体运动响应以及连接件受力情况;对于柔性连接件,考察了拉伸刚度对整个光伏系统力学性能的影响规律。此外,研究了不同环境载荷组合下的多浮体响应特性以及连接件承载能力。研究结果表明,刚性连接件转角约束可有效限制浮体纵荡、纵摇运动,柔性缆绳拉伸刚度在一定范围内影响浮体纵荡响应特性;在两种连接方案下,连接件载荷响应与环境载荷组合有关,光伏系统内外侧连接件分别呈现不同承载力特性。With China's extensive coastline,the potential for offshore photovoltaic capacity is immense,leading to a growing interest in floating photovoltaic platforms.To leverage scale advantages and economic benefits,these platforms are typically designed in a connected array configuration.This study conducts a systematic numerical analysis of floating photovoltaic arrays,investigating both rigid and flexible connector designs.For rigid connectors,the study examines the motion responses of the floating bodies and the forces on the connectors under varying rotation constraints released.In contrast,the impact of tensile stiffness on the mechanical performance of the entire photovoltaic system is explored for flexible connectors.Additionally,the dynamic response characteristics of multiple floating bodies and the load-bearing capacity of the connectors under different environmental load combinations are analyzed.The findings indicate that rotation constraints of rigid connectors can effectively limit the surge and pitch motions of the floating bodies.Furthermore,the tensile stiffness of flexible ropes affects the surge response of the floating bodies within a certain range.The load responses of the connectors in both connection configurations are related to environmental load combinations,exhibiting distinct loadbearing characteristics for the inner and outer connectors of the photovoltaic system.
