Research Progress in Dynamics of Planetary Gear Transmission System

Abstract

In this paper, the research progress of dynamics of planetary gear transmission system is discussed. The dynamic model of planetary gear transmission system and the dynamic characteristics of planetary gear are elaborated emphatically. Three dynamic models of pure torsion, translation-torsion coupling and translation-torsion-axial coupling of planetary gear transmission system are introduced. The research progress of dynamic characteristics of planetary gear transmission system is described from three aspects: inherent characteristics, load sharing characteristics and dynamic response characteristics, and the future research is prospected.
