摘　　要：根据单自由度行星轮系传动链的结构特征,采用信号流图法的基本理论来研究复杂行星轮系传动的功率特性。本文将行星轮系传动特性与信号流图的传递机理相结合,建立了XP型、PX型、T型、Π型和E型混联系统的信号流图模型。再按照信号流图法的简化计算原理,分别得出了这五种混联系统的转速和转矩的计算关系式,然后利用该式分别计算出这五种轮系的功率特性。最后通过实例计算,进一步验证了采用该法计算复杂行星轮系功率特性参数的准确性与可行性。Based on the structural characteristics of the single-degree-of-freedom planetary gear train transmission chain,the signal flow graph method is used to deal with the transmission power characteristics of complex planetary gear train.In this thesis,the transmission characteristics of planetary gear train and the transmission mechanism of signal flow graph are combined to establish the signal flow graph model of XP-type,PX-type,T-type,Π-type and E-type hybrid system,with the simplified principle of signal flow graph method used to acquire the calculation formula for the rotation speed and torque of the five hybrid system.On this basis the power characteristics of the five kind of gear train are calculated.Finally,the accuracy and feasibility of this method are verified by the practical calculation
