摘要: 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Directive 78/2009/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。

Abstract: 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.
