浮标在波浪作用下产生动荷载,具有明显的动力学特征。浮标与波浪相互作用包括浮鼓与海浪的耦合、浮鼓与锚链的耦合,是复杂的多学科的流固耦合问题。基于三维有限元流固耦合算法,建立“浮标—海水—空气—海底”系统模型,仿真了浮标和单列Airy波相互作用,研究了浮标在特定海况下的动力响应,定量地给出浮标的运动规律、自摆周期、锚链拉力、浮筒摆角及设备安装点加速度等重要结论,为浮标设计、制造、运行、维护提供重要参考和依据,也为海上风力发电、海上作业平台和跨海大桥桥墩等波浪作用的动力分析提供了重要参考和借鉴。
Buoys generate dynamic loads under the action of waves, with obvious dynamic characteristics. The buoy-wave interaction includes the coupling of the floating drum with the waves and the coupling of the floating drum with the anchor chain, which is a complicated and multidisciplinary fluid-solid coupling problem. Based on the three-dimensional finite element method, the “buoy-sea-air-seafloor” system model was established and the interaction between buoy and single-row Airy wave was simulated. The dynamic response of the buoy under certain sea conditions was studied. The important conclusions and conclusions are as follows: the law of the movement, the pendulum cycle, the tension of the anchor chain, the swing angle of the buoy and the acceleration of the installation point of the equipment. It provides an important reference and basis for the buoy design, manufacture, operation and maintenance. Sea bridge piers and other wave dynamic analysis provides an important reference and reference.
