基于行人保护的乘用车前部造型设计优化

摘要

The vehicle front-end styling is a key factor for obtaining better performance of pedestrian protection. Based on the Pedestrian Protection Regulation of the European Commission （Directive 78/2009/EC） and the evaluation procedures of pedestrian protection in European New Car Assessment Program （Euro-NCAP） styling design was optimized for the front-end, including the hood, fender, ventilated cover plate, and bumper in a passenger car, using CAS （Computer-Aided Styling）, in consideration of the requirements of head impact areas and leg impact areas. The results show that the optimized front-end styling effectively controls the impact areas, in favor of the pedestrian protection performance improvement, which provides practice in the styling design for new vehicles.%汽车前部造型是获得良好的行人保护性能的关键。基于《欧盟行人保护法规》之条款Directive78／2009／EC及《欧洲新车评价规程》（Euro—NCAP）中的相关规定，运用计算机辅助造型（CAS）技术，考虑到行人保护头部碰撞区域及腿部碰撞区域的划分要求，对某乘用车的前部造型（发动机罩、翼子板、通风盖板和前保险杠）进行优化。结果表明：采用优化后的前部造型有效地控制了碰撞区域，有利于提升该车型的行人保护性能。因此，该结果可为新车造型设计提供参考。
