摘要
介绍了行人保护柔性腿型(Flex-PLI)的伤害指标,建立了有限元的柔性腿型与整车分析模型并进行分析,与刚性腿型(TRL)的伤害指标进行对比分析。研究了柔性腿型在不同撞击位置的分析结果,得出柔性腿型的胫骨弯矩和韧带拉长量这两个伤害指标的影响因素及规律,并对此提出相应的改进措施。
Injury index of pedestrian protection Flex-PLI is introduced. The pedestrian protection lower leg impact model is established with Flex-PLI and compared with TRL. Analysis results on different positions of Flex-PLI are studied. The influential factors and rules of tibial bending and ligaments lengthening are given and improved.
