摘要
本文應用MARC有限元素軟體分析軸對稱冷鍛(Cold Forging)加工問題。首先本文利用軸對稱擠鍛成形(Extrusion Forging)加工實驗，以擠鍛成形力量以及鍛件擠伸高度之成形結果，驗證MARC分析冷鍛加工問題的可靠性與妥適性。
再以此相同加工問題分析方式，探討自行車使用在外變速系統的重要零組件-飛輪(Free Wheel)之中心結構轂體(Hub)採用鍛造加工的成形結果。並分別探討飛輪轂體多道次鍛造加工過程中，胚料成形填充狀態與鍛造加工成形力量分佈情形以及摩擦效應和胚料尺寸效應對成形性的影響。並預測鍛造模具破壞模式與破壞位置，並且以模具材料Strain-Life實驗曲線預測裂縫成長開始之循環週期。
