摘　　要：为改进海上风力机在风浪载荷下的动力学响应特性,提出了新型类龙骨仿生内肋塔架。通过考虑湍流风、波浪载荷和非线性土-构耦合作用的有限元方法模拟塔架动态响应和屈曲特性。结果表明:在风浪载荷作用下,相较于传统塔架,仿生塔架塔顶位移较小,可有效抑制风浪载荷的影响,且应力分布更加合理,高刚度内肋结构可保证塔架的稳定性,但一定程度上会导致局部应力增加;相较于传统塔架,仿生塔架屈曲模态位移相对较小,表明仿生塔架可有效提升塔架的抗失稳能力。In order to improve the dynamic response characteristics of offshore wind turbines under wind and wave loads,a new type of bionic keel-like inner ribbed tower was proposed.The dynamic response and buckling characteristics of the tower were simulated with a finite element approach considering turbulent wind,wave loads,and nonlinear soil-structure coupling.Results show that under the action of wind and wave load,compared with the traditional tower,the displacement of the top of the bionic tower is smaller,which can effectively suppress the influence of wind and wave load,and the stress distribution is reasonable.The high-stiffness inner rib structure can ensure the stability of the tower,but it will lead to the increase of local stress to a certain extent.Compared with the traditional tower,the buckling mode displacement of the bionic tower is relatively small,which indicates that the bionic tower can effectively improve the instability resistance of the tower.
