摘　　要：为探究不同波、流环境耦合作用对网衣系统动力响应的影响,基于集中质量法和网目等效法研究在规则波-流耦合作用下波流方向、水流速度、波高和周期、10种不同网衣破断形式对网衣张力和变形的影响。结果表明:在规则波-流耦合作用下,网衣与刚性框架连接位置和网衣中部受力最大,网衣的4个边角处变形最小,且网衣张力随着流速、波高的增大而增大;在不同的网衣破断形式下,网衣张力只在网的断裂方向上显著减小,而其他方向的张力没有明显变化;对于节点的运动,只在网衣破断周围节点的运动增加,而其他节点的运动并没有明显变化。In order to explore the influence of the coupling effect of different wave and flow environments on the dynamic response of the net system,the effects of wave-current direction,current velocity,wave height and period,and ten different net damage forms on the tension and deformation of the net under the coupling action of regular waves and currents are analyzed based on the lumped-mass method and the equivalent mesh method.The results show that:under the coupling action of regular waves and currents,the connection position between the net and the rigid frame and the middle part of the net experience the maximal force;the deformation at the four corners of the net is minimal,and the tension of the net increases with the increase of current velocity and wave height;under different net damage forms,the tension of the net significantly decreases only in the direction of net damage,while the tension in other directions does not show significant changes;regarding node movement,only the motion of nodes around the damage area of the net increases,while the motion of other nodes does not show significant changes.
