摘要
针对某款混合动力汽车,综合考虑发动机、电机、复合行星齿轮机构、离合器、减速器、差速器和半轴等部件,采用集中质量法建立功率分流传动系统动力学模型。在此基础上,分析不同运行工况下传动系统固有频率和振型,分别研究电机和发动机激振频率与传动系统固有频率之间的关系,仿真分析扭转减振器刚度对传动系统固有频率的影响规律,通过改变扭转减振器刚度从而使得传动系统共振转速远离发动机常用工作区。
For a hybrid electric vehicle,considering the engine,motor,composite planetary gear mechanism,clutch,reducer,differential and half shaft,the dynamic model of power split transmission system is established with the centralized mass method.On this basis,the natural frequency and vibration mode of the transmission system under different operating conditions are analyzed,the relationship between the excitation frequency of motor,engine and the natural frequency of the transmission system is studied respectively,and the influence law of torsional damper stiffness on the natural frequency of the transmission system is simulated and analyzed.Finally,by changing the stiffness of the torsional shock absorber,the resonant speed of the transmission system is adjusted far away from the common working area of the engine.
