海上风机单桩基础防护设施与船舶碰撞分析

Analysis of Collision Between Ship and Protection Facilities for Monopile Foundation of Offshore Wind Turbines

为有效减小船舶等结构碰撞对风机基础结构造成的影响,提出一种针对海上风机单桩基础的防护设施。基于ANSYS/LS-DYNA软件,对4000吨级近海散货船以0.5 m/s、1.0 m/s的速度与防护设施的碰撞过程进行模拟,并对防护设施在受撞击情况下的应力响应进行分析。研究成果可为海上风机基础防护设施的设计工作提供一定参考。

In order to effectively reduce the impact of collision of ships and other structures on the wind turbine foundation,a protection device for the monopile foundation of offshore wind turbine is proposed.Based on ANSYS/LS-DYNA software,the collision process of 4000 t class offshore bulk carrier with protective facilities at the speed of 0.5 m/s and 1.0 m/s is simulated,and the stress response of protective facilities under impact is analyzed.The research results can provide some references for the design of basic protective facilities for offshore wind turbines.
