Finite Element Analysis of Spur Gears on Modal and Stress

Being established and assembled in UG, the model file of spur gears was imported to ANSYS workbench, where the contact between gears was built, meshing completed later. Then support and loads was imposed on the finite element model to obtain characteristics of modal and stress distribution on the teeth. After that they each were compared with working frequency and theoretically maximum contact stress and we found the fact was they fit well. By doing this, it is sound to say finite element analysis of spur gears on modal and stress is effective, feasible and reliable.
