| Abstract: | This article taking the general involute gear as research object,considering time-varying stiffness and fixing damping factor,establishes a vibration differential equation of gear and finds out the dynamic load on the surface of meshing spur gears.A model of gear with a crack in dedendum is established based on ANSYS software.The dynamic load of tooth surface and the dynamic stress intensity factor of the cracked gear tooth are loaded and calculated using APDL language.And the changing regularity is obtained. |

| Keywords: | dynamic load time-varying engaging stiffness stress intensity factor |
