摘　　要：风力发电机塔架结构的自然频率与风轮的工作频率(风叶的通过频率)相近时,将发生共振,导致风力发电机无法正常工作。文章基于动力吸振原理,建立了拉索式小型风力发电机塔架结构等效振动模型,再以6kW级拉索式小型风力发电机塔架结构的缩小模型为对象制作吸振器,用理论与试验验证吸振器的有效性。试验结果表明,吸振器能够有效减少塔架结构共振频域内的振动。When the natural frequency of the tower structure is close to the working frequency of the wind turbine,the resonance occurs.This paper based on the principle of dynamic vibration absorption,build up the theoretical equivalent vibration model of the small size turbine tower structure supported by guy cables.Then developed a vibration absorber which is based on the reduced model of the tower structure of a 6 kW type small wind turbine.The validity of vibration absorber is verified by theory and experiment.The results show that the vibration absorber can effectively reduce the vibration in the resonance frequency domain of the tower structure.
