摘　　要：为探究张力腿式(TLP)风机的运动响应规律,快速获取其结构的动力响应特性,供海上漂浮式风机概念设计参考,对该型风机运动响应的简化模型进行研究。以美国国家可再生能源实验室(NREL)提出的TLP风机为研究对象,基于欧拉-拉格朗日动力方程建立三自由度简化理论模型,求出该模型的位移响应理论解,并将其与OpenFAST数值仿真结果进行对比,验证该简化理论模型的准确性。研究表明,在TLP浮式风机运动幅度较小的情况下,采用简化的理论模型能提高响应的求解效率,同时保证计算精度满足要求。通过该简化模型能快速得到TLP浮式风机结构的动力响应特性,为海洋结构防灾减灾及振动控制研究提供参考。In order to investigate the motion response rule of tension leg platform(TLP)floating wind turbine(FWT)and quickly obtain the dynamic response characteristics of the FWT,and to guide the FWT to carry out the research work of conceptual design.The TLP wind turbine proposed by the National Renewable Energy Laboratory(NREL)is taken as the research object,and a three-degree-of-freedom simplified theoretical model is established based on the derivation of the Euler-Lagrange dynamic equation.The theoretical solution of the displacement response of the simplified model is solved and compared with the numerical simulation results of OpenFAST to verify the accuracy of the simplified theoretical model.The results show that the simplified theoretical model can improve the efficiency of the response solution and ensure the accuracy in the small motion amplitude range of TLP FWT.Through the established simplified model,the dynamic response characteristics of the TLP FWT structure can be obtained quickly,which can provide reference for the future research in disaster prevention and mitigation and vibration control of marine structures.
