摘　　要：动力耦合机构是混合动力汽车主要振动噪声源之一。以某混合动力汽车用双排行星齿轮动力耦合机构为研究对象,建立了行星轮、行星架、齿圈和轴系等部件的三维模型,并用UG装配模块对整个系统进行了装配。通过ANSYS Workbench进行模态分析,得到动力耦合机构前二十阶模态。对动力耦合机构固有频率分析,其振动主要以两行星排中行星轮的扭转振动为主,且固有频率较大,能有效避免与发动机及电机之间产生共振。The power coupling system is one of the main sources of noise and vibration in hybrid electric vehicle. The three- dimensional model of the double planetary gear power coupling systemfor a hybrid electric vehicle is established based on UG. After analyzing the modal inthe ANSYS Workbench, the first twenty order modes of the double planetary gear power coupling system are obtained. Natural frequency of the power coupling system is analyzed. There is a result that the power coupling system vibration is mainly based on the torsional vibration of the planetary gears of the two planets, and their natural frequency is much more than the output excitation frequency, which can effectively avoid the resonance from the engine and the motor.
