微型客車(chē)耐撞性的改進(jìn)方法及應(yīng)用

針對(duì)某微型客車(chē)進(jìn)行了耐撞性分析, 找出其不滿足我國(guó)正面碰撞乘員被動(dòng)安全性法規(guī)要求
的原因, 并對(duì)提高其車(chē)身結(jié)構(gòu)被動(dòng)安全性的方法進(jìn)行了研究。通過(guò)建立相應(yīng)的力學(xué)目標(biāo)和利用計(jì)算機(jī)模擬分析手段, 提出既對(duì)原車(chē)身結(jié)構(gòu)改動(dòng)小, 又能有效提高被動(dòng)安全性的結(jié)構(gòu)改進(jìn)措施。對(duì)該車(chē)改進(jìn)后的結(jié)構(gòu)進(jìn)行了正面碰撞計(jì)算機(jī)模擬和實(shí)車(chē)實(shí)驗(yàn), 模擬結(jié)果和實(shí)驗(yàn)結(jié)果吻合良好。

Abstract: In th is paper, the reason that them inibus did no tmeetw ith the standard and themethods used to imp rove passive safety in frontal impact ofm inibusw ere studied. Based on mechanicsmodeling and computer simulat ion, the m inibus st ructuremodifying technique and designingmethod are put fo rw ard. The result of computer simulat ion of frontal impact is consistent w ith that of experiment fo r the imp roved st ructure.
