In order to explore the differences in response between the finite element (FE) model of pedestrian lower limb and the advanced pedestrian legform impactor (aPLI) during pedestrian protection collision test

based on 2021 China-New Car Assessment Program(C-NCAP)

this paper compared the injury indicators and kinematics responses of the Chinese 50 percentile pedestrian lower limb FE model and the aPLI legform FE model in simplified models of family car (FCR)

multi-purpose vehicle (MPV)

roadster (RDS) and sport utility vehicle (SUV). At the same time

Transport Research Laboratory (TRL) collision simulation was carried out in SUV model to evaluate the damage to the pelvis caused by the front edge of the hood. The results show that there are certain differences in the kinematics response between the pedestrian lower limb FE model and the aPLI in the collision simulation of four different vehicle types. In terms of injury assessment

the maximum tibial bending moment of the pedestrian lower limb FE model is smaller than the aPLI. The maximum femoral bending moment of the pedestrian lower limb FE model without long bone and ligament failures is closer to the aPLI than the lower limb FE with failure; in RDS vehicle collision simulation

there is a significant difference between the maximum femur bending moment of the pedestrian lower limb FE model without failure and the aPLI; the pedestrian lower limb FE model can more comprehensively assess lower limb injuries.
