摘要

最近塑性流動接合技術開始使用於汽車產業中鈑金與螺帽問的接合，經由簡單的工具進行鍛壓，使板材在欲接合處產生塑性流動，而與螺帽接合在一起，不需要焊接或是額外的接合元件，可以有效降低生產成本但接合處的塑性流動，往往是產品好壞的重要關鍵，因此本文就塑性流動接合製程，針對影響接合區流動特性的製程參數，利用FEM軟體進行分析模擬，探討製程參數特性，其結果可提供製程設計之參考。

Recently plastic flow joining is used in joining the metallic sheet and the nut, especially in automobile industries. The joining area is deformed plastically by the simple forging compression tool. This process makes the sheet and the nut joining each other and there is no need for welding or extra joining components. The cost for this process of clinch joining could be down. However, the plastic deformation in the joining area is often the key to the quality of the product. Thus, in this paper, the process parameters which could affect the flow characteristics of the joining area are analyzed by FEM software. The characteristics of the process parameters obtained in this research can be provided for process design.
