目前汽車維修鈑件開發流程中,已經導入逆向工程技術以完成鈑件的CAD數位資料,但若能結合CAE技術,將可使維修鈑件的開發成本與時間降至最低,品質提升至原廠標準。本文即是以鈑金衝壓分析套裝軟體DYNAFORM分析壓料板夾持力、引伸深度、入口R角與壓料條設置對引擎蓋引伸成形的影響,並歸納出一最佳化參數,經過實際衝壓驗證,得到CAE 分析結果與實際引伸成品兩者之間並無太大差異。藉由CAE可在維修鈑件模具設計初期,即可評估鈑件可製造性與模具設計之可行性,在試模階段更可協助找對問題發生的原因與改善對策的擬定。因此在維修鈑件開發中,導入
CAE 技術將可促使維修鈑件產業升級,增加競爭力。
At present, although reverse engineering have been used to create the sheet metal CAD model in developing process of automobile maintenance parts, yet the process will become more streamlined and smooth with considerably improving the quality of the parts of concern If it can combine the CAE technology. The thesis use DYNAFORM to simulation the drawing process and try to find the effect of drawing, like binder force, drawing depth, entry R and draw bead.
Finally, we get the best parameter for hood drawing process.There is no different between CAE model and real parts.
By use CAE technology,in the early stages of the design, you can evaluate sheet metal manufacturability and die design of feasibility, then in the test mode stages can help find the cause of the problem and make the way to deal with a situation for improvement.
