However, in the sheet metal forming technology, wrinkling, rupture, deformation and rebound and other quality problems are more and more prominent, which not only caused a lot of material waste, but also seriously restricted the use of aluminum alloy sheet in the automotive industry The Therefore, to explore a suitable for aluminum alloy sheet stamping of the excellent process, has become the focus of many car manufacturers.In this paper, the finite element analysis software ANSYS Workbench is used to analyze the stamping of aluminum forming components in automobile bumper, and the main factors leading to its quality problems are found out. Combining with the analysis results, the existing stamping process is optimized reasonably, To achieve the purpose of improving the yield.Key words  Finite element analysis  aluminum forming   process optimization目錄第1章 緒論11.1 引言11.2 汽車保險(xiǎn)杠鋁成型組件工藝優(yōu)化的科學(xué)意義11.3 汽車保險(xiǎn)杠鋁成型組件質(zhì)量問(wèn)題的國(guó)內(nèi)外研究狀況11.3.1 國(guó)外研究情況21.3.2 國(guó)內(nèi)研究情況21.4汽車保險(xiǎn)杠鋁成型組件的發(fā)展趨勢(shì)21.5汽車保險(xiǎn)杠鋁成型組件缺陷分析31.5.1起皺31.5.2破裂41.5.3回彈51.6本文研究的主要內(nèi)容51.7本章小結(jié)6第2章 板材沖壓有限元分析理論72.1 ANSYS Workbench軟件介紹72.2 材料的特性72.3 材料的屈服準(zhǔn)則82.3.1 Tresca 屈服準(zhǔn)則82.3.2 Von Mises 屈服準(zhǔn)則92.4材料的硬化準(zhǔn)則92.4.1各向同性硬化準(zhǔn)則92.4.2隨動(dòng)硬化準(zhǔn)則102.5 沖壓過(guò)程應(yīng)力加載和卸載法則112.6 沖壓過(guò)程接觸算法112.6.1 拉格朗日算法122.6.2 罰函數(shù)接觸算法122.6.3 非線性罰函數(shù)接觸算法12第3章 保險(xiǎn)杠組件沖壓成型工藝153.1 保險(xiǎn)杠組件沖壓成型的的工藝特點(diǎn)153.2 保險(xiǎn)杠組件沖壓工藝的詳細(xì)說(shuō)明163.3 本章小結(jié)20第4章 有限元分析過(guò)程及結(jié)果214.1概述214.2 分析流程及結(jié)果214.2.1分析流程214.2.2 分析結(jié)果254.3 本章小結(jié)26第5章 工藝優(yōu)化內(nèi)容及結(jié)果275.1 工藝優(yōu)化的注意事項(xiàng)275.2 工藝優(yōu)化的內(nèi)容275.3 優(yōu)化效果305.4 本章小結(jié)30致  謝31參考文獻(xiàn)32【詳情如下】【需要咨詢購(gòu)買全套設(shè)計(jì)請(qǐng)加QQ1459919609】三維圖.zip上模切邊刀塊.dwg下模廢料刀塊.dwg產(chǎn)品.dwg任務(wù)書(shū).doc沖頭固定座.dwg原創(chuàng)性聲明.doc外文翻譯.docx封面.doc成績(jī)單.doc文件清單.txt有限元分析結(jié)果有限元分析結(jié)果.zip模具裝配圖.dwg汽車保險(xiǎn)杠鋁成型組件有限元分析及工藝優(yōu)化.docx汽車保險(xiǎn)杠鋁成型組件有限元分析及工藝優(yōu)化開(kāi)題報(bào)告.doc汽車保險(xiǎn)杠鋁成型組件有限元分析及工藝優(yōu)化文獻(xiàn)綜述.doc答辯PPT.pptxCAXA副本圖紙.zipFinite Element Analysis and Shape Optimization of Aluminum Alloy Automobile Energy-absorbing Components.pdf 2,a, ,b , 50086, 50086, a In of by a In E of by E of an of in to of of he of an in of As to of in 1, 2. no t s It is to in is of it at of a In it is to be to so of is be 3, 4.
