车辆行人安全技术的研究进展

随着汽车安全研究的深入,行人保护安全技术逐渐成为车辆安全开发的热点。本文在文献研究的基础上,概述了行人安全技术的研究进展,包括行人头部安全技术、行人下肢安全技术,并探讨了行人安全技术的发展趋势。研究结果表明:发动机罩结构及材料设计中考虑行人头部安全成为设计主流,另外随着头部保护范围的扩大,雨刮及发动机罩铰链也都采用了有利于行人头部保护的设计。吸能式前端结构及保险杠设计,降低了行人下肢的伤害。行人安全气囊技术及行人假人技术是行人保护安全技术未来发展的方向。

Development and Research for Pedestrian Safety Technology of Vehicle

With the intensive study of the automotive safety, pedestrian protection safety technology gradually becomes the hot issue of vehicle safety. On the basis of literature research, the research progress of pedestrian safety technology, including the pedestrian head safety technology and the pedestrian leg safety technology, is summarized, and the development trend of the pedestrian safety technology is discussed too.The research results show that the design of engine hood structure and material considering the pedestrian head safety become mainstream design. In addition, with the enlargement of the head protection, wiper and hood hinge are adopted for the design of pedestrian head protection. Energy absorption type front-end structure and bumper design reduce the pedestrian leg injury. Pedestrian airbag and pedestrians＇ dummy technology are the direction of future pedestrian protection safety technology.
