The planetary gear train (PGT) is one of the most important components of the new hybrid and electric vehicles due to its high torque-to-weight ratio and to its compact geometry. However, this system generates a lot of vibrations which increase the noise into the vehicles due to its complex geometry and to its various mesh coupled motion. The aim of this study is to construct a novel torsional coupled vibration model based on bond graph method and to understand the planetary gear train motional and modal behavior with a focus on the damping effect of the meshing while taking into account the damping effect of the bearings that connects the system to the shaft. The result from bond graph is in good agreement with observed result, and it can be seen that bond graph is proper enough to simulate dynamic behavior of PGT compared with the results by a traditional equation of motion.
