英文摘要：

This paper reviews the research situation of domestic and foreign scholars on the aspects of planetary gear trains dynamic model,dynamic response,dynamic load and load sharing,inherent characteristics and dynamic stability.Research findings about two lumped parameter models,solving results of dynamic response by different methods.Theory and experimental investigations of dynamic load and load sharing,laws of inherent characteristics and influence of system parameters on inherent characteristics and dynamic stability are introduced.Finally,according to the development trend of planetary gear trains,several issues for future study are put forward as follows：dynamic characteristics of planetary gear with force of friction and compound planetary gear,vibration control of planetary gear trains.
