摘　　要：建立了双重功率分流系统弹性支承下的力学模型。运用轮齿几何接触分析(TCA)和承载接触分析(LTCA)方法对齿轮副实际啮合过程进行仿真,拟合了齿轮副的时变啮合刚度,提高了计算精确度。根据系统构成功率流闭环的特点推导出系统的变形协调条件,并结合力矩平衡方程和弹性支承条件计算各齿轮副传递的扭矩,得到系统的均载系数。讨论了各种误差对系统功率分流的影响,为双重功率分流传动系统的设计提供了参考。In order to research load sharing characteristics of the dual power-split gear train,the mechanical structure model was established.With the method of the tooth contact analysis and loaded tooth contact analysis,the actual meshing process of gear pair was simulated and the time-varying mesh stiffness was obtained,which can enhance the precision of the computation.According to the closed-loop characteristic of the power flow of the system,the reverse angle deformation coordination conditions were deduced,which were combined with the mechanical equilibrium equations and elastic support conditions to calculate the transfer torque and load sharing coefficient of system.The influences of errors on the power split characteristics were analyzed.It provided an important role in the reference for the design of the dual power-split transmission system.
