摘　　要：利用SolidWorks软件对某型齿轮传动风扇(GTF)发动机的风扇转子系统建立其等效三维模型,导入ABAQUS中对风扇转子进行模态分析。提取了前9阶固有频率及模态振型进行了分析和处理,发现了风扇转子各阶次振型特点和共振频率规律;结合发动机的工作转速和振动安全裕度,验证了风扇转子工作安全转速;通过对比风扇转子各部件的共振频率,发现了GTF发动机风扇转子系统同时包括柔性、刚性轴部件,这主要与GTF发动机风扇转子部件的功能相关。该研究对GTF发动机风扇转子系统的设计与应用提供了参考与理论依据。Based on the 3D software SolidWorks, a model of fan rotor system of a Certain Geared Turbofan(GTF)engine is established and imported into ABAQUS to do the rotor modal analysis. The first 9 natural frequencies and mode shapes are analyzed and processed, and the law and order modes are found;combined with the working speed and engine vibration safety margin, verify the safe speed of the fan rotor system;furthermore, the fan rotor system of GTF engine includes both flexible, rigid shafts witch are related to the function of components. The research can provide reference and theoretical basis for the design and application of the GTF engine fan rotor system.
