为提升车辆撞击事故乘员的安全性,从诱导孔个数、前纵梁材料和梁壁厚三个方面对汽车前纵梁进行了优化设计。将上述三个方面作为影响因素进行了正交试验设计,按照正交表在LS-DYNA当中进行了整车碰撞及台车试验,以头部损伤HIC值作为乘员损伤评价标准,通过极差分析确定了最优汽车前纵梁参数,提高了汽车碰撞中乘员的安全。
為提升車輛撞擊事故乘員的安全性,從誘導孔箇數、前縱樑材料和樑壁厚三箇方麵對汽車前縱樑進行瞭優化設計。將上述三箇方麵作為影響因素進行瞭正交試驗設計,按照正交錶在LS-DYNA噹中進行瞭整車踫撞及檯車試驗,以頭部損傷HIC值作為乘員損傷評價標準,通過極差分析確定瞭最優汽車前縱樑參數,提高瞭汽車踫撞中乘員的安全。

To enhance the security of vehicle crash, the longitudinal beam was optimized in this paper. The induction holes number, materials and thickness were taken as the factors. The vehicle collision test and sled test were simulated in LS-DYNA, according to the orthogonal table. The HIC value was taken as the injuries evaluation criteria. Through the poor analysis, the optimal longitudinal beam parameters were identified, and the occupant safety was improved.
