Abstract:	本文將利用有限元素軟體Deform-3D進行模擬分析，研究上模具運動路徑為行星及螺旋軌跡之旋轉鍛造傘形齒輪，並採用六因子三水準Box-Behnken實驗設計，透過迴歸分析建立二階多項式預測模型，求得齒輪在良好填充率下，應變均勻度最小之最佳化解。結果顯示品質特性之預測模型具有精確度；初步研究最佳化結果顯示行星軌跡優於螺旋軌跡。;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 and spiral on cold rotary forging of a spur bevel gear. Using the Box-Behnken design of experiment, 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.As a result, the prediction model of quality characteristics is accurate. A preliminary study showed the best result that planetary better than spiral.
