摘　　要：利用ANSYS建立了塔架的柔性体模型,并对其进行了模态分析,同时在考虑叶片安装误差引起的不平衡质量的基础上,利用ADAMS建立了把塔架作为柔性体的风力发电机系统的柔性体模型,研究了风速变化和变桨引起的风力发电机塔架上方各部件重心的变化对塔架振动的影响,得到了基于上述因素综合作用下的振动分析和动载荷分析结果,为塔架的优化设计提供了更准确的依据。The flexible body model of the wind turbine tower is established by means of ANSYS, and which modal can be analyzed,meanwhile after the unbalance mass caused by the installment error of the blades is considered,the flexible body model of the wind turbine is established by means of ADAMS, which regards the tower as the flexible body. The wind speed and change of the mass center of all components on the tower,caused by the blade angle ,is also considered,and the impact of which on the vibration of the tower is researched. The results of the vibration and dynamic load analysis based on these factors are obtained,and which are very essential to the optimal design of the tower.
