Abstract
Multiple gear ratios in automatic transmission are achievable with multi-stage planetary gears, where there are both the loaded planetary gear and the idle planetary gear under some gear ratios operation. Due to the change of road conditions, engine runs with different rotational speed and torque, which brings an external fluctuation excitation to the automatic transmission planetary gear set. In addition, the gear backlash becomes larger with the wear increasing during the running. Both engine excitation and gear backlash are important factors that not only influence the vibration characteristic and meshing state of the loaded planetary gear but also those of the idle planetary gear. The objective of this paper was to investigate the change of meshing force state of loaded planetary gear and idle planetary gear influenced by the different backlash and the engine excitation based on a nonlinear torsional vibration model.
