以某兆瓦级风电机组主齿轮箱为研究对象，设计了齿轮箱的行星传动机构。通过三维建模软件Pro-E建立行星架的计算模型，利用ANSYS有限元软件对行星架进行模态分析，选择Block Lanczos提取方法，提取前6阶模态；分析各阶模态的固有频率和振型；在此基础上，对行星架进行谐响应分析，有效地判断出行星架的振动特性。该分析结果为行星架的动力学研究提供了基础，也为风电机组行星架及齿轮传动的设计提供了理论依据。

In this paper, we designed a planetary transmission mechanism for a wind turbine gearbox. The calculation model of planet carrier was built by a 3D modeling software Pro-E, and modal analysis was made by ANSYS software. Block Lanczos extraction method was selected to extract the 6-order mode. Finally we identified the vibration characteristics of planet carrier through the harmonic response analysis and analysis of the inherent frequency and vibration mode for each order. The results provided research basis for dynamics of planet carrier, and for the design of planet carrier and gear transmission of wind turbine.
