摘要针对兆瓦级风力发电机组传动链的复杂性，经过简化，分别建立齿轮箱、弹性元件和机架为系统的单自由度和两自由度振动模型，并根据风机传动链结构的特点，对齿轮箱和弹性元件系统的固有频率和刚度等参数以及传动链结构尺寸和这些参数的相互影响的关系进行分析和研究，提出适合于风机传动链中齿轮箱弹性元件相关参数的基本设计方法；并以齿轮箱为对象在现场进行振动测试，根据齿轮箱结构特点和对应测试数据的相关性两方面对试验结果的合理性进行了详细分析。根据测试结果再分析弹性元件振动特性和隔振效果，验证弹性元件和传动链结构的合理性，为风机设计提供参考。

Abstract：According to the complexity MW wind turbine drive chain，the system of single degree of freedom and two degree of freedom vibration model are established respectively for the gear box, the elastic element and the frame simplified. Through analysis and research on the structure characteristics of the wind turbine drive chain，and the relation between the dimension of the structure and characteristics of the gearbox system corresponding， the design method suitable for the elastic element of wind turbine gearbox transmission chain of the related parameters is put forward. After gear box vibration test at the site，the test data is confirmed from tow hand, the structure of the gearbox and correlation. The vibration characteristics and the effect of vibration isolation of the elastic element are analyzed. Then the elastic element and the drive chain structure are verified .So this methods can be as a reference for the wind turbine design .

Key words： wind turbine flexible element vibration isolation gearbox vibration test
