| Abstract: | By the high performance parallel computer and finite element software ANSYS, a root transition curve and 3D solid model are generated precisely for a gear, and a reliable and high precision finite element mesh model and calculation model is built. The 3D root stress and the tooth deformation of a real gear are simulated and calculated by using 3D isoperimetric elements calculation with twenty nodes. The comparison of the computational error and reliability of 2D model and 3D equivalent model show that the method can provide reference for the calculation of gear root stresses and tooth deformations. |
