塑料前舱盖头部保护C-NCAP五星目标达成

Plastic front hood head protection C-NCAP 5-star target achieved

在车辆与行人碰撞事故中行人属于弱势群体,而且行人头部受到的伤害尤其严重,通过对前舱盖针对性结构设计有利于提高行人头部的保护。采用仿真和试验结合对标的方法,建立行人头部撞击器与发动机罩碰撞的有限元模型,通过模拟头部伤害值得分,对结构设计提出优化改进方向。汽车针对行人的碰撞安全保护已经成为汽车碰撞安全性研究领域的主要一环,其评价方法的完善对促进汽车与行人碰撞安全性的提高具有重要意义。

In the vehicle-pedestrian collision accidents,pedestrians are vulnerable groups,and the head of pedestrians is particularly seriously injured.The targeted structural design of the front cabin cover is conducive to improving the protection of the head of pedestrians.The finite element model of the collision between the pedestrian head impactor and the hood was established by combining the simulation and experiment with the target alignment method.Vehicle pedestrian collision safety protection has become a major part of the research field of vehicle collision safety,and the improvement of its evaluation method is of great significance for promoting the improvement of vehicle and pedestrian collision safety.
