The Dynamics Analysis Study Planetary Gear System Based on the Virtual Prototype Technology

摘要

The torsional vibration model of the planetary gear train has combined with the virtual prototype technology. The dynamics simulation of the planetary gear train is proceeded with by the model established. The model includes both the time varying mesh stiffness and the backlash of the meshing gear pairs. The dynamic characteristic in the transmission can be obtained conveniently and exactly by the model. Thus it can provide a theoretical basic for optimum structure and life prediction of the planetary gear train.
