中文摘要：

针对某款纯电动汽车保险杠轻量化设计的要求与可制造性,设计了一种整体式碳纤维增强树脂基复合材料保险杠,并采用拉丁超立方采样、Kriging近似建模技术与遗传算法进行优化求解.结果表明,优化后的碳纤维增强树脂基复合材料保险杠能够满足耐撞性要求,并达到减重36.4%的轻量化效果.

英文摘要：

An auto bumper used integral carbon fiber reinforced plastic is designed for a type of electric vehicle based on the lightweigh design requirement and manufacturability.The lightweight solution which meets the crashworthiness requirements is obtained through optimization procedure with Latin hypercube sampling,Kriging metamodel and genetic algorithm.The weight of bumper system is reduced by 36.4%.
