| Abstract: | The thesis simulates the process of the spline forming by the FEM software. By studying the distribution of the stress, the fracture in root part of the tooth is testified and the cause is found. Then the possible position of facture may be predicted by analyzing the distribution and change of the critical value. By numerical simulation of a six-tooth rectangle spline, the optimized half-angle of the concave die can be got. |
