Abstract

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.
