| 摘 要： | 以某轿车为研究对象,运用显式有限元理论,建立整车有限元模型,基于“汽车正面碰撞乘员保护设计规则(CMVDR294)”的耐撞安全性仿真,从满足整车正面耐撞安全性能的角度,分别采用高强钢和铝合金对车身主要覆盖件进行轻量化研究,使车身减质量分别达9.31kg和53.10 kg,减质量效果达到11.30%和64.50%。对整车变形、整车与刚性墙的碰撞力、运动速度和加速度、主要零部件吸能等方面进行分析、评价,数值仿真验证了轻量化方案的可行性。

| Abstract: | Finite element theory is applied and the new style passenger car is used as the prototype, when using high strength steel and aluminum alloy to lighten auto-body, the total weight can be reduced 9.31 kg, 53.10 kg and the lightweight effect is 11.31%, 64.50%. Based on carshworthiness simulation according to CMVDR294, compared the deformation of entire car, the crash force to the rigid wall, velocities, accelerations, and energy-absorbing ability of main parts, the results of crashworthiness simulation verified the feasibility of the proposed method. |
