Abstract
On the basis of Lagrangian equation, the pure torsional vibration model of a vehicle powertrain containing multistage planetary gears was established and used to investigate the similarity of natural characteristics when system was in different conditions. By using the real modal theory, the sensitivities of natural frequency to moment of inertia and stiffness were calculated and analyzed when system under a normal condition. The distribution law of natural frequency and the influence of the physical parameter on the natural frequency were obtained. Because of the change of torsional stiffness of joining in multistage planetary gears transmissions, the phenomenon of frequencies loci veering exists. The influence of frequencies loci veering on natural characteristic was discussed simply. It provides theoretical guidance for the dynamic analysis of multistage planetary gears.
