台风环境中典型海上风机结构的动力响应数值分析
|
摘要
基于COMSOL有限元软件,计算分析台风环境中风机结构承受的风荷载、波浪荷载和流荷载,建立典型大直径单桩与导管架基础风机结构简化模型,分析台风极端工况下风机桩基泥面和轮毂点的转角与位移动态响应,为台风环境中海上风机基础选型提供建议。
Based on finite element software COMSOL,the wind load,wave load and current load acted on the wind turbine under typhoon are calculated.The simplified model of wind turbine with large diameter monopole and jacket foundation is established.The dynamic responses of the rotation and displacement at seabed and the hub are analyzed.The analysis provides recommendation for the selection of wind turbine foundation under typhoon.
