摘　　要：以流体机械流动相似理论为基础,提出了风力机械相似准则,并确立了风力机相关参数的相似关系。依据所得到的风力机相似关系,详细推理了风力机原型与模型的应力关系及固有频率关系,得出了风力机尺寸缩放对其力特性的影响关系,并给出了相似理论在风力机中应用的局限。可供风力机的设计参考。On the basis of flow similarity, the similar rule of wind turbine can be determine. And, the similar relation of parameter on wind turbine was established. According to this similar relation, the stress and natural frequency relation between prototype and model of wind turbine was given. We get the change of the dynamics characteristic when the dimension of wind turbine Enlarge （or reduce） and find the limit of similarity theory when it is applied in wind turbine. This will offer a new way and reference value for the design of wind turbine.
