| Abstract: | The key technologies of the dynamic simulation analysis of the spur gear contacts by the LS-DYNA finite element analysis software are studied in this paper. The tooth face contact stress, the strain changes and the distribution of the pair of gears in the meshing process are calculated. The weakest parts of gear contact arc found and modified. It＇s of great significance for these to improve the intensity gear tooth contact and the smooth transfer of the movement. |
