| 摘 要： | 近海风电机组的支撑结构承受风机载荷和风、浪、流等环境载荷的作用。基于动量-叶素理论得出发电机的控制策略,根据随机瞬时风速序列和发电机运行状态计算了近海风电机组单桩式支撑结构所受的风机载荷和风压作用,并通过Morison公式计算了浪流联合作用对支撑结构的载荷。用ABAQUS软件对支撑结构和海底土层建模,通过振型叠加法计算结构的动力响应,求出了结构顶端位移和速度以及结构最大应力的时间历程,并研究各种载荷对结构的影响。结果表明,风机载荷是结构动力响应的关键影响因素。

| Abstract: | Offshore wind turbine support structure is subjected to turbine loads and environment loads caused by wind,wave and current.According to the stochastic transient sequences of wind speed and the running condition of the turbine,turbine loads and wind pressure of offshore wind turbine mono-pile support structure are calculated.The loads caused by wave and current are also worked out through Morison equation.ABAQUS is used to model the support structure and the seabed.The dynamic response was calculated throug... |
