摘　　要：在分析基本行星排运动特征的基础上，将机构分解为仅有两个共同点的子系统，并对子系统再进行分解，直到每个子系统仅为一个基本行星排为止，用基本行星排的传动比表示机构的传动比．本文详细讨论了机构中各离合器处于不同工作状态时传动比的求法，该方法简单、明了、实用．On the basis of analysis of kinematics characteristics of FGEs,the mecbanism is decomposed into two subsystems which are connected to each other by only two common nodes, and each subsystem is further decomposed until the subsystem contains only one FGE. Overall speed ratios of epicyclical gear train is expressed in terms of the speed ratios of the FGEs. This paper discussed a computation method in detail which determines various speed ratios when various clutching conditions of mechanism. The method is simple,concise and practicable.
