Based on the concentrated mass method

the domestic and foreign development situation of gear system dynamics is expounded in detail

around the development process of the gear dynamics

on the basis of gear system dynamics equation

firstly

from the vibrational excitation

research goal

the analysis theory

the mathematical model and solving method

the research progress of gearsystem dynamics are reviewed.Secondly

according to the existing research results of gear system dynamics

the application of dynamics on gear engineering is analyzed.Finally

according to the development trend of gear system dynamics research

the problems which need to be studied furtheris put forward.
