| Abstract: | The basic principle of modal analysis is briefly introduced, the straight tooth cylindrical gear solid model is estab-lished by using 3D Pro/ E software, the process of gear modal analysis is described based on finite element analysis software ANSYS in detail which including the unit type selection, definition of material properties, meshing, constraint, mode settings. And the influence of the number of teeth, modulus, tooth width is analyzed on gear mode, especially the influence on the nat-ural frequencies. |
