Abstract：To a planetary reducer with small tooth number difference, a coupling multi-body dynamics virtual prototype model was established, the dynamic correlation method was used to validate the virtual prototype model and the accuracy of the virtual prototype model was verified; the equivalent stress and vibration response of planetary reducer were analyzed under various conditions, and its vibration characteristics were tested by vibration test equipment. The results show that with the increase of rotational speed of the planetary reducer, the equivalent stress has no distinct change, but the eccentric motion of the eccentric shaft is increasingly obvious, which enhances impact to meshing gear leading to more serious vibration and impact amplitude, the simulation analysis results are consistent with the experimental results.
