This study examines the mechanisms behind in-phase and sequential-phase configurations in planetary gear systems and the effects of meshing phase on noise and vibration performance. In these systems, simultaneous meshing of multiple gear teeth results in repetitive dynamic interactions. Therefore, it is crucial to design these systems to effectively cancel the interaction energies of the gear teeth. The meshing phase is primarily influenced by the number of teeth on the sun and ring gears, the number of pinion gears, and the circumferential arrangement of the pinions on the carrier. Analysis of an 8-speed automatic transmission demonstrates that a sequential-phase configuration can reduce second harmonic planetary gear noise and vibration by up to 25 dB relative to in-phase configurations. Therefore, at the concept design stage, avoiding in-phase arrangements by appropriately selecting gear tooth numbers and pinion counts is essential to reducing planetary gear noise and vibration. Furthermore, effective noise and vibration reduction requires phase optimization that considers at least the second harmonic component.
