摘　　要：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 solving its dynamic equations with the fourth order Runge-Kutta method, the dynamic load mesh sharing damping. Through 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 baeklashes 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.
