1、鹽城工學(xué)院本科生畢業(yè)設(shè)計說明書2007“遠(yuǎn)艦”轎車雙擺臂懸架的設(shè)計及產(chǎn)品建模摘要：汽車雙擺臂懸架是一種常見的懸架形式，合理的選擇懸架的結(jié)構(gòu)和幾何尺寸是獲得滿意的汽車行駛性能的重要條件，其運動特性的優(yōu)劣關(guān)系到汽車操縱穩(wěn)定性，舒適性，轉(zhuǎn)向輕便性和輪胎的使用壽命等性能。本課題來源于東風(fēng)悅達(dá)起亞汽車制造有限公司的遠(yuǎn)艦款轎車的后懸架，雙擺臂懸架可以通過合理的選擇空間導(dǎo)向桿系的鉸接點的位置及導(dǎo)向臂的長度，使得懸架具有合適的運動特性。在設(shè)計中，首先，分析了雙擺臂獨立懸架的組成和功用；其次，進行雙擺臂懸架的上下擺臂及各零部件強度的校核；第三，詳細(xì)考慮各部件之間的連接關(guān)系；最后計算

2、了懸架自然振動頻率，懸架靜撓度和動撓度以及懸架彈性特性。在分析雙擺臂懸架的組成和作用以及確定各零部件的尺寸的基礎(chǔ)上，運用CAD軟件和Pro/E軟件分別進行二維繪圖和三維建模。此次課題進行了準(zhǔn)確的計算和詳細(xì)的結(jié)構(gòu)分析，為雙擺臂懸架的結(jié)構(gòu)優(yōu)化提供了依據(jù)，從而在運動學(xué)和動力學(xué)方面提高汽車的性能。關(guān)鍵詞：雙擺臂懸架；汽車；設(shè)計；建模全套CAD圖紙，聯(lián)系33鹽城工學(xué)院本科生畢業(yè)設(shè)計說明書2007TheDesignandProductmodelingofDoubleWishboneSuspensionof“Optima”CarAbstract：Thedouble-wishbo
