Abstract
In order to research the seismic dynamic response of the structure for ogshore wind turbine with bucket foundation, the sail-structure interaction(SSI) is considered with the equivalent linear dynamic constitutive model that can reflect the non-linearity and hysteresis of soil on the basis of the subroutine UMAT provided by ABAQUS, and then a finite element and infinite element coupling model for analysis on the rotor blade, tower, bucket foundation and soil is established for a domestic offshore wind power generation system; furthermore, the dynamic response analysis is made with the lime domain analysis based on i static analysis. The study shows that the natural frequency of the structure can be reduced by SSi eSect Lnder the seismic dynamic effect, the maximum horizontal acceleration response gf the tower structure of the wind turbine occurs near 1/3 height of it, while the vertical acceleration response keeps increasing all along the tower height and its amplification effect is stronger than that of the horizontal one.关键词
