摘 要:本文針對(duì)保險(xiǎn)杠的結(jié)構(gòu)設(shè)計(jì),提出了一套基于空氣動(dòng)力學(xué)的前保險(xiǎn)杠側(cè)角風(fēng)道空氣優(yōu)化設(shè)計(jì)方案。經(jīng)驗(yàn)證,該方案既可有效降低風(fēng)阻、減少燃油消耗,也可增加保險(xiǎn)杠側(cè)邊的結(jié)構(gòu)強(qiáng)度,提升前保險(xiǎn)杠的穩(wěn)定性,降低成本。
關(guān)鍵詞:風(fēng)道 風(fēng)阻 保險(xiǎn)杠 成本 強(qiáng)度

Sun Jinxing Yuan Shaopeng Zhu Shaohong Chen Yujuan Sun Tupeng Fan Zengyan
Abstract:This article describes an aerodynamic optimization design of the side air duct of the front bumper. The design can not only reduce the wind drag, reduce fuel consumption, but also increase the strength of the side at the bumper, improve the stability of the front bumper, reduce the cost and increase the strength of the structure.
Key words:air curtain, wind drag, bumper, cost, strength.
