關鍵字:旋轉鍛造、有限元素分析、傘形齒輪 ;An ideal FE model of cold rotary forging of a spur bevel gear is developed under the Deform-3D software and the upper die motion path on filling rate and equivalent strain uniformity are in this study. The six factors in the design include the work-piece geometry and the rotary forging process parameters. The work-piece geometry such us piece volume V, Lower height〖 h〗_1, the diameter of the upper and lower diameter〖 d〗_1 〖、d〗_2 and the rotary forging process parameter such us the process parameter with feed amount of per revolution S , and inclination angle of the upper die γ.The experiment adopts 49 groups of analogs with the Box-Behnken design. Use the Minitab software to do the regression analysis and develop the predicted equations. By doing so, it’s excepted using the FEM model and surface response methodology to find the optimum design of the filling rate and equivalent strain uniformity . In this paper filling rate and strain uniformity prediction equation established with the results of finite element simulations to verify the results show the prediction model with considerable accuracy.
