摘　　要：为研究海上风机高桩承台基础受到船舶碰撞作用的动力响应,本文运用非线性分析软件LS-DYNA,结合我国东南某海上风电场实际情况,通过建立风机高桩承台基础与船舶碰撞的有限元模型,研究了船舶在撞击过程中的撞击力时程分布以及高桩承台基础在撞击作用下的响应,分析了船舶碰撞对于风机基础结构的动力影响,对于橡胶护舷对于基础结构的保护作用进行了分析。研究结果表明,船舶撞击速度对于风机基础结构的位移影响显著,需要严格控制船舶靠泊速度。同时,橡胶护舷对于结构起到了良好的保护作用。In order to study the dynamic response of the offshore high-pile concrete cap wind turbine foundation subjected to the collision of the ship.The nonlinear analysis software LS-DYNA,combined with the actual situation of an offshore wind farm in southeast China,is used to establish a finite element model of the collision between the high-pile concrete cap wind turbine foundation and the ship.The time history distribution of the impact force of the ship during the collision,as well as the response of the foundation under impact is studied.The dynamic impact of the ship collision on the wind turbine foundation structure is analyzed.The results show that the impact speed of the ship has a significant impact on the displacement of the wind turbine base structure,and the ship's berthing speed needs to be strictly controlled.At the same time,the rubber fender has a good protective effect on the structure.
