| Popis: | 104 In this paper, the FEM simulation model of cold rotary forging is established under Deform-3D software environment. the upper die motion path is a planetary on cold rotary forging of a spur bevel gear. To investigate the quality design of spur bevel gear, the filling rate of lower die cave and equivalent strain coefficient of variance are quality goals based on the following quality factors: blank volume(V), the diameter of upper blank(d_1), the diameter of lower blank(d_2), the height of lower blank(h_1), feeding rate(S) and the angle of upper die( ). Using the Box-Behnken design of experiment [36], through the regression analysis to build a prediction model of second-order polynomial function. Regression analysis simulation result to obtain gears at the optimization in minimum equivalent strain coefficient of variance and good filling rate. The paper shows the prediction model of quality characteristics is accurate. |
