摘要
混合动力汽车传动系统相较于传统燃油汽车结构更为复杂,其传动系统在多动力源复杂激励下扭转振动问题更加突出。针对某款P2构型混合动力汽车,综合考虑发动机、电机、无级变速器、离合器、减速器、差速器和半轴等部件,采用Simcenter Amesim软件建立混合动力汽车传动系统集中质量模型。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,研究激振源频率与传动系统固有频率之间的关系。仿真分析离合器一级弹簧刚度、二级接触刚度对传动系统固有频率的影响规律,通过优化刚度参数从而使得传动系统共振转速远离激振源常用工作区。
Compared with the traditional fuel vehicle,the structure of the transmission system of hybrid electric vehicle is more complex,and the torsional vibration of its transmission system under the complex excitation of multiple power sources is more prominent.In this paper,for a P2 hybrid electric vehicle,considering the engine,motor,composite planetary gear mechanism,clutch,reducer,differential and half shaft,the centralized mass model of hybrid electric vehicle transmission system is established with Simcenter AMESim software.On this basis,the natural frequency and vibration mode of the transmission system under different operating conditions are analyzed,and the relationship between the excitation source frequency and transmission system natural frequency is studied.The influence of the first spring stiffness and the second contact stiffness of the clutch on the natural frequency of the transmission system is simulated and analyzed.The stiffness parameters of the clutch are optimized so that the resonant rotating speed of the transmission system is far away from the common working area of the excitation source.
