基于集中参数，建立了双输入圆柱齿轮分流传动系统的弯扭耦合动力学模型，模型中考虑了各齿轮副间的齿侧间隙、时变啮合刚度、啮合阻尼等因素。采用四阶龙格-库塔法，求解系统动力学方程，获得了系统的动力学均载系数。分析了齿侧间隙对均载系数的影响，获得了齿侧间隙对分流级、并车级均载系数的变化规律。研究结果表明：分流级均载系数随分流级单分支齿侧间隙增加而增大，随分流级双分支齿侧间隙增加而减小；分流级单分支、双分支齿侧间隙对并车级均载系数影响较小；并车级均载随并车级单分支齿侧间隙增加而增大，随并车级双分支齿侧间隙增加而减小；并车级单分支、双分支齿侧间隙对分流级均载系数影响较小；动载系数随双分支齿侧间隙的增加而增大。

Based on the method of lumped parameters,a dynamic model was established for a 2-input cylindrical gear split-torque transmission system considering time-varying mesh stiffness,backlashes and mesh damping.Through solving its dynamic equations with the fourth order Runge-Kutta method,the dynamic load sharing coefficients of the system were acquired.The results showed that the load sharing coefficient of the split-torque stages increases with increase in backlash of single branch in split-torque stages,and it decreases with increase in backlash of dual-branch in split-torque stages;the backlashes of single-branch and dual-branch in split-torque stages have a smaller impact on the load sharing coefficient of synthesized torque stages;the load sharing coefficient of the synthesized torque stages increases with increase in backlash of single branch in synthesized torque stages,and it decreases with increase in backlash of dual-branch in synthesized torque stages;the backlashes of single-branch and dual-branch in synthesized torque stages have a smaller impact on the load sharing coefficient of split-torque stages;the dynamic load coefficient increases with increase in backlash of dual-branch.
