摘　　要：|采用信号流图法研究混联行星轮系传动特性参数的灵敏程度和调速特性。依据信号流图法的简化规则,建立XP型和P X型混联行星轮系传动特性的信号流图模型及计算模型。采用微分灵敏度法,分别对构成混联系统中的封闭轮系和行星轮系的传动特性进行参数灵敏度分析,得出混联轮系的参数敏感区域及灵敏程度。采用单参数和多参数结合法,对XP型和P X型混联行星轮系的调速特性进行分析,得出XP型轮系传动的调速速率与相关参数变化具有高度耦合性,而P X型轮系的调速速率与相关参数变化具有单调性的结论。A signal-flow chart has been used to see data sensibility and gear reduction features of the composite type planetary transmission system, respectively. According to abridge rule of the signalflow chart models of XP type and PX type have to be built for the transmission features and for computation, respectively. Differential sensitivity has been used to analyze features of closure section and planetary section in the composite drive system, respectively, in terms of parametric sensitivity, before getting sensitivity zones and degrees.By combining singular parameter with multiple parameters to analyze drive features of the 2 models we see that the XP model's reduction speed ratio has high coupling capability with relative parameters while the PX model's has only monotony as concluded.
