To study the dynamics characteristics of planetary gear coupling driving system, the dynamics simulation and analysis are performed on the system using MapleSim. The planetary gear system model is built in MapleSim and the dynamics equations of the system are derived based on machine symbols. Considering time-variant engagement stiffness, the dynamic load factor of the gear engagement is calculated and the dynamic load processes are obtained under the single input or the double inputs. The results indicate that the correct dynamics equations can be obtained quickly by machine symbols, which make it easier to study the dynamics of the system.
