摘　　要：文章利用梁单元对海上风力机筒形塔架进行有限元建模,并建立了塔架动力学运动方程。阐述了海上风力机塔架所受Kaimal湍流风模型和Pierson-Moskowitz波浪谱模型,并对风载荷、波浪载荷和海流载荷进行了详细分析。基于某6.0 MW海上大型风力机塔架的动力响应计算,分析了极限和疲劳工况下波浪对塔架顶端振动位移和塔底载荷的影响程度,为海上风力机筒形塔架设计提供了参考。The tubular tower of offshore wind turbine was modeled by applying beam element for finite element modeling,and the dynamic equation of tower was established.The Kaimal turbulent wind model and the Pierson-Moskowitz wave model were presented firstly,then the wind,wave and sea current loads were analyzed in details.The influence of wave acting on the top vibration deflections and the bottom loads of the offshore tower were analyzed in the extreme and fatigue cases based on calculating dynamic response of a 6.0 MW offshore wind turbine,providing some theoretical basis for the design of the offshore tubular tower.
