摘要:随着风力发电机塔架高度的增加和叶片尺寸的增大,高耸支撑塔架在风荷载作用下将产生显著的动力响应和大幅变形,甚至可能发生疲劳、屈曲、倾斜或倾覆等事故。本文以1.5 MW风力发电机结构为例,利用ABAQUS软件建立有限元模型,对未减振以及安装单质量调频质量阻尼器(STMD)、双质量调频质量阻尼器(BTMDs)、四质量调频质量阻尼器(QTMDs4 种方案在风荷载作用下的振动响应进行模拟研究,以便对振动控制方法选择提出可行性建议,有效降低事故发生的概率。结果表明,与未减振时相比,安装STMD时风机塔架顶点加速度峰值减小37. 89% ;在仅有低阶振型作用下,STMD对风机结构的减振控制有较好的效果,且优于BTMDs QTMDs

Abstract:The increases of height and blade size of the wind turbine structure and the high-rise tower structures may generate obvious dynamic responses and large amplitude displacements even happen with fatigue buckling sloping or overturning accidents under wind load. In this paper taking a wind turbine structure of 1.5 MW as an example the finite element model under wind load was established with ABAQUS software to analyze the vibration responses under the non-controlled status compared with other schemes of installing single tuned mass damper STMD bi-tuned mass dampers BTMDs and quad-tuned mass dampers QTMDs so as to put forward feasible suggestions for vibration control methods and effectively reduce the probability of accidents. The numerical results showed that when STMD was installed the peak acceleration on the top of the wind turbine tower decreased by 37. 89% . Compared with non-controlled status STMD had a good effect on the vibration control of the wind turbine and the damping effect of installing STMD was better than BTMDs and QTMDs under the action of only low-order vibration mode.
