摘　　要：为改善Spar平台承载的漂浮式风力机的力学性能和运动性能,运用数值计算方法研究附加螺旋侧板前后结构的动态特性变化,并对比不同螺圈数目的螺旋侧板对结构性能的影响。通过水动力计算得到附加螺旋侧板前后结构的频域和时域动态特性曲线,对比结果表明:附加螺旋侧板后结构的力学性能和运动性能均得到有效改善;对比不同螺圈的结果,1螺圈和2螺圈的螺旋侧板具有相对更好的改善作用。In order to improve the mechanical property and kinematic performance of Spar-supported offshore wind turbine, dynamic characteristics of the platform attached with helical strakes were researched through numerical calculation method and further compared the influence of the number of helical strakes. Frequency-domain and time- domain dynamic performances were obtained through hydrodynamic calculation, and the results showed that both mechanical property and kinematic performance have been efficiently improved when the platform are attached with helical strakes. In addition, the comparison of different numbers of helical strakes indicates that the structure has better improvement when the number is 1 and 2.
