1、畢業(yè)論文（設(shè)計(jì)）題目9m空氣懸架大客車后懸架設(shè)計(jì)系部汽車與交通工程系9m空氣懸架大客車后懸架設(shè)計(jì)汽車懸掛系統(tǒng)設(shè)計(jì)【摘要】：懸掛系統(tǒng)是指由車身與輪胎間的彈簧和避震器組成的整個(gè)支持系統(tǒng)。懸掛系統(tǒng)的功能是支持車身，改善乘坐的感覺，不同的懸掛設(shè)置會(huì)使駕駛者有不同的駕駛感受。外表看似簡(jiǎn)單的懸掛系統(tǒng)綜合多種作用力，決定著轎車的穩(wěn)定性、舒適性和安全性，是現(xiàn)代轎車十分關(guān)鍵的部件之一。論文回顧了汽車懸掛系統(tǒng)的發(fā)展歷程，介紹了懸掛系統(tǒng)的分類和組成，詳細(xì)分析了各種懸掛系統(tǒng)的優(yōu)劣，進(jìn)行了對(duì)比。最后根據(jù)汽車的要求，選定了懸掛系統(tǒng)的組合，前懸架為麥弗遜式獨(dú)立懸掛，后懸架為
2、鋼板彈簧整體式懸掛。并且確定了前后懸掛的技術(shù)參數(shù)，在設(shè)計(jì)中著重考慮了汽車的穩(wěn)定性和操控性，對(duì)整個(gè)系統(tǒng)進(jìn)行了運(yùn)動(dòng)學(xué)和力學(xué)分析計(jì)算。最后使用AUTOCAD繪制出了汽車懸掛的裝配圖和部分零件圖?！娟P(guān)鍵字】:汽車懸掛獨(dú)立懸掛非獨(dú)立懸掛麥弗遜式獨(dú)立懸掛鋼板彈簧整體式懸掛III9m空氣懸架大客車后懸架設(shè)計(jì)TheDesignOfCarSuspensionSystem【Abstract】Suspensionismeansthatthebodyandtiresbetweenspringandshockabsorberfortheentiresupportsyst
