摘　　要：针对某5 MW半潜式风力机的振动控制进行研究,以单纯形遗传算法(SCGA)分别对有无行程限制的调谐质量阻尼器(TMD)的固有频率、阻尼比进行参数优化,探讨经过优化参数后的TMD对风力机关键部位位移和载荷的影响。在SIMPACK软件中建立半潜式海上风力发电机组的多体动力学模型,在5种工况下对风力发电机进行动力学仿真分析。仿真结果表明,相较于有行程限制的TMD,施加行程限制后的TMD减振效果变差,但考虑到机舱空间的实际大小,TMD施加行程限制仍有一定的参考意义,且纵向减振效果优于横向减振效果。In this paper,the vibration control of the semi-submersible wind turbine is studied.Taking a 5 MW semisubmersible offshore wind turbine as an example,based on the simple coding genetic algorithm(SCGA),the natural frequency and damping ratio of the tuned mass damper(TMD)with stroke limitation and no stroke limitation is optimized.The influence of TMD on the displacement and load of the key position of the wind turbine is discussed.The multi-body dynamic model of semi-submersible offshore wind turbine is established in SIMPACK software.Under five conditions,the wind turbine model is simulated.The simulation results show that effect of TMD with stroke limitation is worse than that with no stroke limitation.But considering the real size of the nacelle space,TMD stroke limitation still has certain reference significance,and the longitudinal vibration damping effect is better than that of lateral vibration reduction effect.
