摘　　要：针对柔性薄膜式海上漂浮式光伏结构,开展了不规则波作用下薄膜式结构运动响应和系泊力的物理模型试验研究。选取2个不规则波、3个波浪入射角度,分析了在不规则波作用下柔性薄膜式海上漂浮式光伏结构浮圈和薄膜上各点的运动响应,同时测量了系泊力。试验结果表明,柔性薄膜式结构的垂向运动呈现较好的随浪性,各测点的垂向运动有效值约等于不规则波的有效波高,但最大值有较强的非线性,水平运动受波浪入射角度影响较大。随着入射角度从0°增大到45.0°,4条系泊缆受力不均匀性逐渐增加,在迎浪侧系泊缆出现最大系泊力172.80 kN的工况,此时背浪侧的最大系泊力仅为81.52 kN,不到迎浪侧最大系泊力的二分之一。This study investigates the motion response and mooring forces of flexible membrane-type offshore floating photovoltaic structures under irregular wave conditions through physical model experiments.Two types of irregular waves and three wave incidence angles were selected to analyze the motion responses of various points on the flexible ring and membrane of the flexible membrane structure,while also measuring the mooring forces.The experimental results indicate that the vertical motion of the flexible membrane structure exhibits favorable wave-following behavior,with the effective values of vertical motion at each measurement point approximately equal to the effective wave height of the irregular waves;however,the maximum values exhibit significant nonlinearity.The horizontal motion is greatly influenced by the wave incidence angle.As the incidence angle increases from 0°to 45.0°,the nonuniformity of the tension in the four mooring lines gradually increases,with the maximum mooring force of 172.80 kN occurring on the wave-facing side,while the maximum mooring force on the back-wave side is only 81.52 kN,which is less than half of that on the wavefacing side.
