风机结构在地震作用与风荷载下多灾害响应分析
Analysis of multiple disaster response of fan structure under seismic action and wind load
摘要
Abstract
With the increasing demand for wind energy,wind farms are increasingly being developed in regions with strong winds and high seismic activity.When onshore wind turbines are subjected to earthquake,they must typically endure wind loads simultaneously,making it essential to examine their multi-hazard response under combined seismic and wind loading.In this study,an operational wind turbine located in Shanxi Province was selected for analysis.The probability of current seismic and hazards was assessed,and a finite element model was developed.Three sets of natural ground motion records were used to evaluate the structural response of the wind turbine under seismic loading alone and under combined seismic and wind loading,in order to investigate the effect of wind load on the response increases significantly with rising wind speed,while the influence of wind load on the seismic response tends to diminish as the peack ground acceleration increases.This indicates that the dominant control on the structural response shifts from wind load to seismic load as earthquake intensity increases.关键词
