Abstract：Aiming at the problem of the gear mesh was affected by time varying loads which lead to gear surface fatigue damage and

shock，the dynamic characteristics of gear and modification were carried out. The coupled model of rigid and flexible was built by

ADAMS，and then the different time-varying loads were obtained based on different modification methods. Finally，modal analysis and

dynamic stress behavior were carried out by ANSYS Workbench. The results indicate that the long parabolic modification is better than

that of short arc modification in the process of alternating two and three pairs of teeth meshing of helical gear，which can provide the

effective basis for gear dynamics analysis.
