| 摘 要： | 风力机是一个刚柔耦合的多体系统，作用在风力机上的空气动力、惯性力和弹性力等交变载荷会使系统产生变形或振动，影响风力机的正常运行，严重时会导致风力机损坏，为此振动稳定性成为机组设计首要关注和解决的问题.从机组的振动原因分析入手，研究了主要振动源的动力学方程，对塔架进行了Campell共振图分析，用有限元分析方法计算出塔架的固有频率和振型，为机组设计提供了依据，通过在线振动监测手段验证了设计的有效性.

| Abstract: | For the variable speed operation of large scale wind turbine,the vibration and correspondingly caused load are key problems that can not be ignored.Both vibration analysis and monitoring for a large wind turbine were discussed.Firstly,the vibration reason and excitation resource of large variable speed wind turbine were analyzed.Secondly,dynamic equations and tower Campell diagram were proposed.Thirdly,the natural frequcy and excited frequency of tower were analyzed by finite element method.Finally,the design safety and validity were verified by online vibraton monitoring. |

| Keywords: | variable speed adjustable pitch wind turbine vibration monitoring on line Campell analysis |
