摘要
在乘用车正面碰撞过程中,为了保护乘员避免受到下肢韧带断裂,瘫痪等严重伤害,中国新车评价规程(C_NCAP)设定了评价假人大腿部位的损伤指标。为了提高在C_NCAP汽车碰撞试验中的大腿部位得分,本文展开了假人腿部伤害机理、影响因素,分析方法的研究,并着重介绍了仪表板子系统膝碰评价方式,同时还以某车型膝碰问题改善为例介绍了膝碰研究成果在实际中的应用。
In order to protect the occupant from serious injuries such as rupture and paralysis of lower limb ligaments during the frontal collision of passenger cars,the C_NCAP(Chinese New Car Assessment Program)sets the injury criteria of the dummy’s femur and knee.In order to improve the scores in the C_NCAP,the injury mechanism,the influencing factors and the analysis method of the dummy knee impact are studied in this paper.The instrument panel subsystem evaluation method of the knee impact is also introduced,and citing a troubleshooting as an instance to introduce the application of knee impact research in practice.
