The effect of aerodynamic imbalance on fatigue performance of wind turbine foundation
摘要
Abstract
To explore the effect of aerodynamic imbalance on fatigue performance of wind turbine foundation with embedded steel ring.Taking the 2 MW wind turbine with embedded steel ring as the research object,the finite element model of the wind turbine was established.Based on the SCADA operation data of the wind turbine in one year,the fatigue life and reliability of foundation fatigue dangerous points were analyzed by the P-M linear cumulative damage criterion and probability density evolution method.The results revealed that the aerodynamic imbalance would significantly increase the stress amplitude of the structure,reduce the fatigue life and reliability of the structure,and have the greatest impact on the foundation concrete,followed by the embedded steel ring,and the reinforcement cage was the smallest.When there was a serious aerodynamic imbalance,the foundation would be damaged in a short time.关键词
