Dynamics and efficiency of planetary gear sets for hybrid powertrains

comprises a six degree-of-freedom torsional multi-body dynamic system, as well as a tribological contact model in order
to evaluate the lubricant film thickness, friction and efficiency of the meshing gear teeth contacts. The tribological model
takes into account the non-Newtonian, thermal-mixed elastohydrodynamic regime of lubrication. Analysis is performed
for a hybrid electric C-segment vehicle. The simulated conditions correspond to cases of power supplied by either the
engine or the electric motor. The results illustrate that in the electric motor drive mode, improved noise, vibration and
harshness refinement would be expected, whereas better transmission efficiency is achieved in the internal combustion
engine drive mode.
