英文摘要：

Planetary gear train mechanism anal- ysis and synthesis method is proposed for the type and dimension synthesis. The topological transformation is used to convert the topology diagram into actual gear train system. The transformation of gear, tied, shaft as well as special auxiliary member changes is proposed. The kinematics and dynamics analysis methods of planetary gear trains are presented based on topology diagram and signal flow diagram and the generation condition of cycle power for planetary gear trains is also discussed.
