摘　　要：以某款双行星排式混合动力耦合机构为研究对象,结合其结构特点及不同工况运行下的工作模式,运用图论理论中的基本回路法进行双行星排式动力耦合机构的运动学分析,实现双行星排式混合动力耦合机构动力部件在不同工作模式下的运动学求解。采用Romax软件进行双行星排式混合动力耦合机构建模,代入不同工作模式下双行星排式混合动力耦合机构部件的运动学关系,对混合动力耦合机构不同工作模式下的功率流传递路径进行效率特性仿真计算,求解结果对制定双行星排式混合动力汽车的最优控制策略以及匹配整车关键部件的参数具有重要意义。Taking a double planetary row type hybrid coupling mechanism as the research object,combining the structural characteristics of the double planetary row type dynamic coupling mechanism and the working mode under different operating conditions,the basic circuit method in graph theory is used to carry out the double planetary row kinematics analysis of the kinematic coupling mechanism to realize the kinematics solution of the power components of the double planet row hybrid coupling mechanism under different working modes.Romax softwareis used to model the double planetary row hybrid coupling mechanism,the kinematic relationship of the components of the double planetary row hybrid coupling mechanism is substitutedunder different working modes,and the efficiency on the power flow transmission path of the hybrid coupling mechanism under different working modes is performed.The characteristic simulation calculation and the solution result are of great significance for formulating the optimal control strategy of the double planet row hybrid electric vehicle and matching the parameters of the key components of the vehicle.
