An Investigation into Suitable Friction Factor and Optimized Forming Process of 6061 Aluminum Alloy Bicycle Stem

摘要

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.
