摘　　要：腐蚀影响海上风电机组动态响应特性,为评估和预测多腐蚀期龄海上风电机组动态力学行为及疲劳寿命,基于Lagrange方程以及均匀腐蚀模型,建立腐蚀-浮式风电机组参数模型,采用数值分析方法分析多腐蚀期龄海上风电机组动态响应特征。结果表明,随着腐蚀期龄的逐渐累积,塔筒弯曲频率响应幅值成为影响塔顶位移运动的主要因素,塔基弯曲应力呈指数型增长,塔筒疲劳寿命将急剧降低。Corrosion affects the dynamic response characteristics of offshore wind turbines.In order to evaluate and predict the dynamic mechanical behavior and fatigue life of multi-corrosion aged offshore wind turbines,the parametric mathematical model of corrosion-floating wind turbines was established based on Lagrange equation and homogeneous corrosion model to analyze the dynamic response characteristics of multi-corrosion-aged offshore wind turbines.The results show that with the accumulation of corrosion age,the amplitude of bending frequency response becomes the main factor affecting the displacement movement of the tower top,the bending stress of the tower increases exponentially,and the fatigue life of the tower decreases sharply.
