An Investigation into Suitable Friction Factor and Optimized Forming Process of 6061 Aluminum Alloy Bicycle Stem
6061鋁合金自行車豎管適當摩擦因子與最佳成形加工
摘要
金屬成型加工中摩擦因子是一個重要的參數，同時影響胚料在模具中成形的過程，本文透過環壓試驗探討AL6061鋁合金摩擦因子，結合實驗與模擬的壓縮率來繪製曲線圖並得知摩擦數值，最後以DEFORM^(TM)3D軟體分析各實驗參數對自行車豎管鍛壓成形之影響，並探討豎管成型之等效應力、等效應變、軸向力、速度場及成形尺寸之比較，期望分析結果能穩定有限元素軟體對自行車豎管成形之可行性。

The friction factor is a crucial parameter in metal forming, and it affects the billet forming process. This paper discusses the AL6061 aluminum friction factor based on the results of a ring crush test. Experimental and simulation compression ratios were combined in this study to draw graphs by using these friction values. Finally, DEFORM^(TM)3D software was used to analyze the impact of the various experimental parameters that were involved in forming a bicycle stem, to explore the effective stress, effective strain, axial force, velocity field, and observed micro-grain products, and to simulate and conduct size comparison experiments. The results of the analysis can be used to stabilize the finite element software that is used to form bicycle stems.
