On mathematical representation of part deformations based on actual working conditions

Based on the basic theory of finite element, the part deformations under the mechanical load are calculated. By combining the theory of TTRS, we present the mathematical expression of part deformations. First we establish solid model of the part through three-dimensional modeling software. We also set material properties and divide the grid. According to the actual working condition of the part, we apply corresponding load for computation model. Finally we use finite element analysis software ANSYS Workbench to solve the part deformations under actual engineering conditions. The method is applied to the analysis of deformations for a gear shaft. The effectiveness of this method is also verified.
