Euro-NCAP行人保护试验协议V7.0解析

Analysis of Euro-NCAP Pedestrian Protection Testing Protocol V7.0

为更准确地给主机厂开发欧洲市场提供帮助,解读了最新的Euro-NCAP行人保护试验协议。通过对比分析了行人保护试验协议V7.0和V6.0之间的主要差异,发现多处内容有所更新,包括试验区域的标记、划分、网格点和评分等。对某车型的行人下腿部进行仿真分析,分析了新旧协议的不同点,以及新版协议V7.0所带来的挑战。最后针对最新Euro-NCAP行人保护协议提出相应的应对措施,比如行人头部、上腿部和下腿部3个碰撞位置所对应的前部车身结构设计开发策略和建议。

The latest Euro NCAP pedestrian protection assessment is studied to appropriately provide the manufacturers with information for developing the European market. By analyzing the main differences between two versions of pedestrian protection test protocols, V7.0 and V6.0, it is found that some testing procedures and related assessments are updated, including grading and tagging of the test zones, the grid points, and scoring system. The pedestrian lower leg impact against a sample vehicle is simulated with the old and new testing protocols. The difference in pedestrian safety assessment is identified and the challenge from the latest protocol is revealed as well. Finally based on the latest Euro NCAP pedestrian protection assessment, the corresponding countermeasures are recommended, such as the body structure design and development strategies for the vehicle front end design, which is involved when the impact is against the pedestrians＇ head, upper leg or lower leg.
