摘　　要：传动链是大型风力发电机组非常关键的组件,对其动力学性能进行深入的分析研究,对风机设计和风电机组产品的传动链振动控制都有重要的意义。从多体动力学(MBS)角度出发,结合转子动力学、模态理论,以SIMPACK专业动力学软件作为仿真平台,对某型2 MW风电机组传动链建立高精度动力学模型,分析系统的特征频率,评估传动链的动力学行为以及传动链的共振特性,并通过现场机组试验验证分析结果。Drive Train is a key component. It is very important to analysis of dynamic for design and control on drive train vibration of wind turbine. So,from the multi body dynamics（ MBS） perspective,combined with the theory of rotor dynamics and modal,SIMPACK professional dynamics software as a simulation platform,a certain type of 2 MW wind turbine high precision drive chain model was established. Then,the characteristic frequency and the kinetic properties of the drive train were analyzed.Last,the analytical results were verified through site test unit.
