| 海上漂浮式光伏系统（FPV）具有节约土地资源、提高发电效率以及促进多产业融合等优势，在海洋工程领域展现出巨大发展潜力。由浮力材料与金属光伏支架构成的FPV平台，作为典型的刚柔耦合结构，在应对复杂海洋环境荷载时，结构易遭受破坏且对连接器要求极高，其在实际工程应用中面临着较大挑战。采用物理模型试验对一种海上漂浮式光伏综合平台（OFPV-X）的运动及结构响应开展深入研究。探讨波浪激励频率、连接器等要素对OFPV-X运动响应的影响，并分析结构应力分布特征，以确定相对最优的平台连接方案。结果表明：波浪砰击与甲板上浪导致OFPV-X发生水弹性响应，平台被激发出复杂的局部振动模式；采用4个刚性连接器方案的双体平台在运动与结构响应性能方面均表现较优；OFPV-X单体结构的前中部模块，尤其是上部结构，会引起显著的结构响应；OFPV-X双体结构上部支架的高应力区域主要分布在迎浪侧平台，尤其是连接器附近。研究成果可为该平台优化设计提供基准数据，并为此类刚柔耦合结构的相关研究提供参考。 |

| Offshore floating photovoltaic (FPV) systems offer advantages in conserving land resources, enhancing power generation efficiency, and fostering cross-industry integration, showing great potential in marine engineering. As a typical rigid-flexible coupled structure, an FPV platform composed of buoyant materials and metal PV mounts is prone to structural damage and places high demands on connectors when subjected to complex marine loads, posing significant challenges in practical applications. In this paper, the motion and structural responses of an offshore floating photovoltaic integrated platform (OFPV-X) are examined in detail through physical model tests. The effects of wave excitation frequency, connectors, and other factors on the motion response of the OFPV-X are explored, and the structural stress distribution characteristics are analysed to determine the relatively optimal connection scheme. The results show that wave slamming and on-deck waves induce hydroelastic responses in the OFPV-X, exciting complex local vibration modes; the double-body platform with four rigid connections performs better in both kinematic and structural responses; the front and middle modules of the OFPV-X single-body platform, especially the superstructure, experience significant structural responses; and the high-stress regions of the OFPV-X double-body platform are mainly distributed on the wave-facing side, particularly near the connectors. The findings provide essential data for optimizing platform design and serve as a reference for related studies on rigid-flexible coupled structures. |
