摘 要
 汽車(chē)問(wèn)世已一個(gè)多世紀(jì)了 ,給世界帶來(lái)了巨大的變化。隨著人民生活水平的提高,汽車(chē)已進(jìn)人平常百姓家,人們對(duì)汽車(chē)的要求也越來(lái)越高,美觀性和安全性已成主題。保險(xiǎn)杠是汽車(chē)車(chē)身的一個(gè)重要部件 ,其除起裝飾作用外 ,還起保護(hù)翼子板 、散熱器和燈具的作用。
 由于保險(xiǎn)杠具有這些功能,國(guó)內(nèi)外對(duì)它的研究十分重視 ,特別是轎車(chē)保險(xiǎn)杠,眾多廠家更是追求造型優(yōu)美、結(jié)構(gòu)獨(dú)特和具有被動(dòng)安全裝置的保險(xiǎn)杠。汽車(chē)保險(xiǎn)杠安裝在汽車(chē)的最前端和最后端 ,在整車(chē)造型風(fēng)格中起到至關(guān)重要的作用。它能夠詮釋出整車(chē)外裝飾的藝術(shù)風(fēng)格 ,好的保險(xiǎn)杠能夠使用戶(hù)感到賞心悅目,得到美的享受。無(wú)論汽車(chē)的大、小改型設(shè)計(jì),保險(xiǎn)杠總是成為造型師手中重點(diǎn)塑造的對(duì)象 ,造型美觀是整車(chē)的亮點(diǎn)及賣(mài)點(diǎn)。
 另外,發(fā)生碰撞時(shí) ,大多數(shù)情況下都有保險(xiǎn)杠的參與,保險(xiǎn)杠作為安全防護(hù)裝置是現(xiàn)代汽車(chē)結(jié)構(gòu)的重要組成部分,它能有效地減輕人員傷亡程度以及汽車(chē)損壞程度。
 本文針對(duì)一款小型車(chē)進(jìn)行了適合小型車(chē)的低成本保險(xiǎn)杠設(shè)計(jì)。在本設(shè)計(jì)中，作者利用PRO\E三維制圖軟件進(jìn)行設(shè)計(jì)，著重強(qiáng)調(diào)了對(duì)保險(xiǎn)杠外形曲面以及連接結(jié)構(gòu)的設(shè)計(jì)，在保證了保險(xiǎn)杠裝配和裝飾性能基礎(chǔ)上盡可能降低成本，從而達(dá)到設(shè)計(jì)目的。
