摘　　要：针对冰区海上单桩风电基础冰激振动问题,提出适用于该类结构的冰振控制措施,设计适用于该类结构的阻尼隔振体系,简化该体系的力学模型,明确体系参数与阻尼比的关系。利用ANSYS数值模拟分析风电基础结构在典型冰况下的减振效果,优化该阻尼隔振控制装置的设计参数。结果表明:阻尼隔振层刚度系数至少为0.6倍的塔筒刚度系数时,阻尼隔振体系与原结构动力特性相似,满足设计要求。Aiming at the ice-induced vibration problem of offshore wind turbine foundation with single pile in ice zone,the strategy of mitigation vibration for this kind of structure is discussed.The simplified mechanical model of damping vibration isolation system is established and the relationship between damping layer parameters and structural damping ratio is analyzed.The vibration reduction effect of wind turbine infrastructure is analyzed by using ANSYS numerical simulation under typical ice conditions,and the parameters of the damping vibration isolation device are optimized.The results show that when the stiffness coefficient of the damping isolation layer is at least 0.6 times that of the tower,the dynamic characteristics of the damping isolation system are similar to those of the original structure and meet the design requirements.
